Following changes done for the framework:
- Framework for creating React based dynamic form view out of a pre-defined UI schema. Previously, it was based on Backform/Backbone.
- The new framework and components will use MaterialUI as the base. Previously, Bootstrap/Backform/jQuery components were used.
- The new code uses JSS instead of CSS since material UI and most modern React libraries also use JSS. In the future, this will allow us to change the theme in real-time without refresh.
- 90% code covered by 80-85 new jasmine test cases.
- Server group node UI Schema migration to new, with schema test cases.
- Server node UI Schema migration to new, with schema test cases.

3) Right-click on a table with vacuum options set and create a new table.
4) The parameters tab will have the options prefilled.
5) Changed the UI a bit to remove unnecessary space around. Added "Autovacuum" before enabled.
The SQL generated was appending a ".0" to decimal vacuum options. Changed to remove the leading ".0".

Query tool.
Graphical

Analysis
--------
-> Table to show details of the explain plan analyse.
-> Each row represents the statistics per Explain Plan Node
-> It may contains columns like node information, exclusive timing
(time spent for this explain node excluding the child nodes),
inclusive timing, actual rows, plan rows,
rowsx (misestimation between planned vs actual rows), loop.
-> Background color of exclusive, inclusive, rows changes based on

If planner misestimation for the rows is

workaround rendering speed issues in CodeMirror with very large scripts.
Fixes#4631.
Re-arrange editor options in the Preferences dialogue to tidy things up.
Attached is a tiny but very effective patch to improve the speed of
finding a node using path (used internally).
If you right click or just click on a node, internally the node is
traversed using its path. But currently, it compares with the path of
all the open nodes to find a match.
So if you 1000+ tables and the tables node is open and if you click on
a view, the view path is compared with all the 1000+ tables (and with
any other open nodes above) before arriving to path. You're at bad luck
if you have more open servers above.
Code is changed to check if the path of node to be found starts with the
current node path. If it doesn't match, why bother the children's of
current node.
This change will not show much effect for small data, but it does matter
for large servers.
One more change is to remove unnecessary calls to find node and use the
data available with Main Menu -> Object to enable/disable node context
menu items.

When a query is run in the Query Tool, check if the source of the columns
can be identified as being from a single table, and that we have all
columns that make up the primary key. If so, consider the resultset to
be editable and allow the user to edit data and add/remove rows in the
grid. Changes to data are saved using SAVEPOINTs as part of any
transaction that's in progress, and rolled back if there are integrity
violations, without otherwise affecting the ongoing transaction.

A powerful, but user-friendly Backup and Restore tool provides an easy way to
use pg_dump, pg_dumpall, and pg_restore to take backups and create copies of
databases or database objects for use in a development environment.
Using the *pg_dump* utility, *pgAdmin* provides an easy way to create a backup in a plain-text or archived format. You can then use a client application (like *psql* or the *Query Tool*) to restore a plain-text backup file, or use the Postgres *pg_restore* utility to restore an archived backup. The *pg_dump* utility must have read access to all database objects that you want to backup.
*pgAdmin* uses the *pg_dump* utility to provide an easy way to create a backup

*psql* or the *Query Tool*) to restore a plain-text backup file, or use the
Postgres *pg_restore* utility to restore an archived backup. The *pg_dump*
utility must have read access to all database objects that you want to back up.
You can backup a single table, a schema, or a complete database. Select the name of the backup source in the *pgAdmin* tree control, right click to open the context menu, and select *Backup...* to open the *Backup* dialog. The name of the object selected will appear in the dialog title bar.

:align:center
Use the fields in the *General* tab to specify parameters for the backup:
* Enter the name of the backup file in the *Filename* field. Optionally, select the *Browser* icon (...) to the right to navigate into a directory and select a file that will contain the archive.
* Use the drop-down listbox in the *Format* field to select the format that is best suited for your application. Each format has advantages and disadvantages:
* Enter the name of the backup file in the *Filename* field. Optionally, select
the *Browser* icon (...) to the right to navigate into a directory and select
a file that will contain the archive.
*Select *Custom* to create a custom archive file that you can use with *pg_restore* to create a copy of a database. Custom archive file formats must be restored with *pg_restore*. This format offers the opportunity to select which database objects to restore from the backup file. *Custom* archive format is recommended for medium to large databases as it is compressed by default.
*Use the drop-down listbox in the*Format* field to select the format that is
best suited for your application. Each format has advantages and
disadvantages:
* Select *Tar* to generate a tar archive file that you can restore with *pg_restore*. The tar format does not support compression.
* Select *Plain* to create a plain-text script file. A plain-text script file contains SQL statements and commands that you can execute at the *psql* command line to recreate the database objects and load the table data. A plain-text backup file can be edited in a text editor, if desired, before using the*psql* program to restore database objects. *Plain* format is normally recommended for smaller databases; script dumps are not recommended for blobs. The SQL commands within the script will reconstruct the database to the last saved state of the database. A plain-text script can be used to reconstruct the database on another machine, or (with modifications) on other architectures.
* Select *Directory* to generate a directory-format archive suitable for use with *pg_restore*. This file format creates a directory with one file for each table and blob being dumped, plus a *Table of Contents* file describing the dumped objects in a machine-readable format that *pg_restore* can read. This format is compressed by default.
* Select *Custom* to create a custom archive file that you can use with
*pg_restore* to create a copy of a database. Custom archive file formats
must be restored with *pg_restore*. This format offers the opportunity to
select which database objects to restore from the backup file. *Custom*
archive format is recommended for medium to large databases as it is
compressed by default.
*Use the *Compression Ratio* field to select a compression level for the backup. Specify a value of zero to mean use no compression; specify a maximum compression value of 9. Please note that tar archives do not support compression.
* Use the *Encoding* drop-down listbox to select the character encoding method that should be used for the archive.
* Use the *Number of Jobs* field (when applicable) to specify the number of tables that will be dumped simultaneously in a parallel backup.
* Use the dropdown listbox next to *Rolename* to specify the role that owns the backup.
*Select *Tar* to generate a tar archive file that you can restore with
*pg_restore*. The tar format does not support compression.
Click the *Dump options* tab to continue. Use the box fields in the *Dump options* tab to provide options for *pg_dump*.
* Select *Plain* to create a plain-text script file. A plain-text script file
contains SQL statements and commands that you can execute at the *psql*
command line to recreate the database objects and load the table data. A
plain-text backup file can be edited in a text editor, if desired, before
using the *psql* program to restore database objects. *Plain* format is
normally recommended for smaller databases; script dumps are not
recommended for blobs. The SQL commands within the script will reconstruct
the database to the last saved state of the database. A plain-text script
can be used to reconstruct the database on another machine, or (with
modifications) on other architectures.
* Select *Directory* to generate a directory-format archive suitable for use
with *pg_restore*. This file format creates a directory with one file for
each table and blob being dumped, plus a *Table of Contents* file
describing the dumped objects in a machine-readable format that
*pg_restore* can read. This format is compressed by default.
* Use the *Compression Ratio* field to select a compression level for the
backup. Specify a value of zero to mean use no compression; specify a maximum
compression value of 9. Please note that tar archives do not support
compression.
* Use the *Encoding* drop-down listbox to select the character encoding method
that should be used for the archive.
* Use the *Number of Jobs* field (when applicable) to specify the number of
tables that will be dumped simultaneously in a parallel backup.
* Use the dropdown listbox next to *Rolename* to specify the role that owns the
backup.
Click the *Data/Objects* tab to continue. Use the fields in the *Data/Objects*
tab to provide options related to data or pgAdmin objects that correspond to *pg_dump*.

If pgAdmin displays this message, there are two possible reasons for this:
* the database server isn't running - simply start it.
* the server isn't configured to accept TCP/IP requests on the address shown.
For security reasons, a PostgreSQL server "out of the box" doesn't listen on TCP/IP ports. Instead, it must be enabled to listen for TCP/IP requests. This can be done by adding **tcpip = true** to the postgresql.conf file for Versions 7.3.x and 7.4.x, or **listen_addresses='*'** for Version 8.0.x and above; this will make the server accept connections on any IP interface.

Use the *Domain* dialog to define a domain. A domain is a data type definition that may constrain permissible values. Domains are useful when you are creating multiple tables that contain comparable columns; you can create a domain that defines constraints that are common to the columns and re-use the domain definition when creating the columns, rather than individually defining each set of constraints.

Use the field in the *Definition* tab to choose a template from the drop-down listbox:
:alt:FTS dictionary dialog definition tab
:align:center
*Select *ispell* to select the Ispell template. The Ispell dictionary template supports morphological dictionaries, which can normalize many different linguistic forms of a word into the same lexeme. For example, an English Ispell dictionary can match all declensions and conjugations of the search term bank, e.g., banking, banked, banks, banks', and bank's. Ispell dictionaries usually recognize a limited set of words, so they should be followed by another broader dictionary; for example, a Snowball dictionary, which recognizes everything.
*Select *simple* to select the simple template. The simple dictionary template operates by converting the input token to lower case and checking it against a file of stop words. If it is found in the file then an empty array is returned, causing the token to be discarded. If not, the lower-cased form of the word is returned as the normalized lexeme. Alternatively, the dictionary can be configured to report non-stop-words as unrecognized, allowing them to be passed on to the next dictionary in the list.
*Select *snowball* to select the Snowball template. The Snowball dictionary template is based on a project by Martin Porter, inventor of the popular Porter's stemming algorithm for the English language. Snowball now provides stemming algorithms for many languages (see the Snowball site for more information). Each algorithm understands how to reduce common variant forms of words to a base, or stem, spelling within its language. A Snowball dictionary recognizes everything, whether or not it is able to simplify the word, so it should be placed at the end of the dictionary list. It is useless to have it before any other dictionary because a token will never pass through it to the next dictionary.
*Select *synonym* to select the synonym template. This dictionary template is used to create dictionaries that replace a word with a synonym. Phrases are not supported (use the thesaurus template (Section 12.6.4) for that). A synonym dictionary can be used to overcome linguistic problems, for example, to prevent an English stemmer dictionary from reducing the word Paris to pari.
*Select *thesaurus* to select the thesaurus template. A thesaurus dictionary replaces all non-preferred terms by one preferred term and, optionally, preserves the original terms for indexing as well. PostgreSQL's current implementation of the thesaurus dictionary is an extension of the synonym dictionary with added phrase support.

*Use the *Estimated cost* field to specify a positive number representing the estimated execution cost for the function, in units of cpu_operator_cost. If the function returns a set, this is the cost per returned row.
* Use the *Estimated rows* field to specify a positive number giving the estimated number of rows that the query planner should expect the function to return. This is only allowed when the function is declared to return a set. The default assumption is 1000 rows.
* Move the *Leak proof?* switch to indicate whether the function has side effects. The default is *No*. This option can only be set by the superuser.
* Move the *Returns a Set?* switch to indicate if the function returns a set
that includes multiple rows. The default is *No*.
*Move the *Strict?* switch to indicate if the function always returns NULL
whenever any of its arguments are NULL. If *Yes*, the function is not executed
when there are NULL arguments; instead a NULL result is assumed
automatically. The default is *No*.

In a Server Deployment, the pgAdmin application is deployed behind a webserver or with the WSGI interface.
If you install pgAdmin in server mode, you will be prompted to provide a role name and pgAdmin password when you initially connect to pgAdmin. The first role registered with pgAdmin will be an administrative user; the administrative role can use the pgAdmin *User Management* dialog to create and manage additional pgAdmin user accounts. When a user authenticates with pgAdmin, the pgAdmin tree control displays the server definitions associated with that login role.

In a *Desktop Deployment*, the pgAdmin application is configured to use the
desktop runtime environment to host the program on a supported platform.
Typically, users will install a pre-built package to run pgAdmin in desktop
mode, but a manual desktop deployment can be installed and though it is more
difficult to setup, it may be useful for developers interested in understanding
how pgAdmin works.
