`Database Dialog`:index:
|
|
************************
|
|
|
|
Use the *Database* dialog to define or modify a database. To create a database,
|
|
you must be a database superuser or have the CREATE privilege.
|
|
|
|
The *Database* dialog organizes the development of a database through the
|
|
following dialog tabs: *General*, *Definition*, *Security*, and *Parameters*.
|
|
The *SQL* tab displays the SQL code generated by dialog selections.

|
|
:align: center
|
|
|
|
Use the fields in the *General* tab to identify the database:
|
|
|
|
* Use the *Database* field to add a descriptive name for the database. The name
|
|
will be displayed in the *pgAdmin* tree control.
|
|
* Select the owner of the database from the drop-down listbox in the *Owner*
|
|
field.
|
|
* Store notes about the database in the *Comment* field.
|
|
|
|
Click the *Definition* tab to continue.
|
|
|
|
.. image:: images/database_definition.png
|
|
:alt: Database dialog definition tab
|
|
:align: center
|
|
|
|
Use the *Definition* tab to set properties for the database:
|
|
|
|
* Select a character set from the drop-down listbox in the *Encoding* field.
|
|
The default is *UTF8*.
|
|
* Select a template from the drop-down listbox in the *Template* field. If you
|
|
do not specify a template, the database will use template1.
|
|
* Select a tablespace from the drop-down listbox in the *Tablespace* field. The
|
|
selected tablespace will be the default tablespace used to contain database
|
|
objects.
|
|
* Select the collation order from the drop-down listbox in the *Collation* field.
|
|
* Select the character classification from the drop-down listbox in the
|
|
*Character Type* field. This affects the categorization of characters, e.g.
|
|
lower, upper and digit. The default, or a blank field, uses the character
|
|
classification of the template database.
|
|
* Specify a connection limit in the *Connection Limit* field to configure the
|
|
maximum number of connection requests. The default value (*-1*) allows
|
|
unlimited connections to the database.
|
|
|
|
Click the *Security* tab to continue.
|
|
|
|
.. image:: images/database_security.png
|
|
:alt: Database dialog security tab
|
|
:align: center
|
|
|
|
Use the *Security* tab to assign privileges and define security labels.
|
|
|
|
Use the *Privileges* panel to assign privileges to a role. Click the *Add* icon
|
|
(+) to set privileges for database objects:
|
|
|
|
* Select the name of the role from the drop-down listbox in the *Grantee* field.
|
|
* Click inside the *Privileges* field. Check the boxes to the left of one or
|
|
more privileges to grant the selected privilege to the specified user.
|
|
* Select the name of the role from the drop-down listbox in the *Grantor* field.
|
|
The default grantor is the owner of the database.
|
|
|
|
Click add to set additional privileges; to discard a privilege, click the trash
|
|
icon to the left of the row and confirm deletion in the *Delete Row* popup.
|
|
|
|
Use the *Security Labels* panel to define security labels applied to the
|
|
database. Click the *Add* icon (+) to add each security label selection:
|
|
|
|
* Specify a security label provider in the *Provider* field. The named provider
|
|
must be loaded and must consent to the proposed labeling operation.
|
|
* Specify a a security label in the *Security Label* field. The meaning of a
|
|
given label is at the discretion of the label provider. PostgreSQL places no
|
|
restrictions on whether or how a label provider must interpret security
|
|
labels; it merely provides a mechanism for storing them.
|
|
|
|
To discard a security label, click the trash icon to the left of the row and
|
|
confirm deletion in the *Delete Row* popup.
|
|
|
|
Click the *Parameters* tab to continue.
|
|
|
|
.. image:: images/database_parameters.png
|
|
:alt: Database dialog parameters tab
|
|
:align: center
|
|
|
|
Use the *Parameters* tab to set parameters for the database. Click the *Add*
|
|
icon (+) to add each parameter:
|
|
|
|
* Use the drop-down listbox in the *Name* field to select a parameter.
|
|
* Use the *Value* field to set a value for the parameter.
|
|
* Use the drop-down listbox next to *Role* to select a role to which the
|
|
parameter setting specified will apply.
|
|
|
|
Follow these steps to add additional parameter value definitions; to discard a
|
|
parameter, click the trash icon to the left of the row and confirm deletion in
|
|
the *Delete Row* popup.
|
|
|
|
Click the *SQL* tab to continue.
|
|
|
|
Your entries in the *Database* dialog generate a SQL command (see an example
|
|
below). Use the *SQL* tab for review; revisit or switch tabs to make any changes
|
|
to the SQL command.
|
|
|
|
Example
|
|
*******
|
|
|
|
The following is an example of the sql command generated by user selections in
|
|
the *Database* dialog:
|
|
|
|
.. image:: images/database_sql.png
|
|
:alt: Database dialog sql tab
|
|
:align: center
|
|
|
|
The example creates a database named *hr* that is owned by *postgres*. It
|
|
allows unlimited connections, and is available to all authenticated users.
