`External database for pgAdmin user settings`:index:
|
|
****************************************************
|
|
|
|
The user settings used by pgAdmin are stored in a SQLite database. In this
|
|
database, many settings are stored, such as preferences, user accounts,
|
|
auto-discovered servers, and many more.
|
|
|
|
As SQLite is a file-based database and it can be anywhere in the file system,
|
|
so it is not designed to take care of failures (no HA support). Furthermore,
|
|
it isn't designed to handle multiple connections concurrently reading/writing
|
|
data to it. Example: In environments such as Kubernetes it may be useful to
|
|
use an alternate backend to avoid using SQLite on non-ephemeral storage and to
|
|
allow HA of the settings database.
|
|
|
|
In order to prevent this, pgAdmin now supports storing user settings in an
|
|
external database using the new 'CONFIG_DATABASE_URI' parameter in the
|
|
:ref:`config.py <config_py>` file.
|
|
|
|
Use SQLite Database
|
|
*******************
|
|
|
|
In order to use SQLite Database, make sure CONFIG_DATABASE_URI parameter is
|
|
set to an empty string like ''. By default it is set to an empty string in the
|
|
config.py so if you would like to use SQLite database then no need to change
|
|
anything.
|
|
|
|
Use External Database
|
|
*********************
|
|
|
|
In order to use an external database, make sure CONFIG_DATABASE_URI parameter
|
|
is set like "dialect+driver://username:password@host:port/database".
|
|
|
|
**Note** It is recommended to create the database in advance.
|
|
|
|
Use PostgreSQL Database
|
|
***********************
|
|
|
|
Following are the formats to use PostgreSQL as an external database.
|
|
|
|
Basic syntax:
|
|
|
|
.. code-block:: bash
|
|
|
|
postgresql://username:password@host:port/database
|
|
|
|
Using specific schema (It is recommended to create the schema in advance):
|
|
|
|
.. code-block:: bash
|
|
|
|
postgresql://username:password@host:port/database?options=-csearch_path=<schema name>
|
|
|
|
Using default pgpass path for the service account:
|
|
|
|
.. code-block:: bash
|
|
|
|
postgresql://username@host:port?options=-csearch_path=<schema name>
|
|
|
|
Specifying pgpass file path:
|
|
|
|
.. code-block:: bash
|
|
|
|
postgresql://username@host:port?passfile=<path of the pgpass file>&options=-csearch_path=<schema name>
