Managing Postgres extensions

Suggest edits

BigAnimal supports many Postgres extensions. See Postgres extensions available by deployment for the complete list.

Extensions available when using your cloud account

Installing many Postgres extensions requires superuser privileges. The table in Postgres extensions available by deployment indicates whether an extension requires superuser privileges. If you're using your cloud account, you can grant superuser privileges to edb_admin so that you can install these extensions on your cluster (see superuser).

EDB extensions:

  • index_advisor
  • refdata
  • autocluster
  • edb_pg_tuner

Installing extensions

Use the CREATE EXTENSION command to install extensions, except for the EDB Postgres Tuner (pg_tuner) extension. You enable edb_pg_tuner on the DB Configuration tab of the Create or Edit Cluster page of the BigAnimal portal.

Example: Installing multiple extensions

This example shows one way of installing multiple extensions simultaneously.

  1. Create a text file containing the CREATE EXTENSION command for each of the extensions you want to install. In this example, the file is named create_extensions.sql.

    CREATE EXTENSION <extension_name_1> SCHEMA <schema_name>;
CREATE EXTENSION <extension_name_2> SCHEMA <schema_name>;
CREATE EXTENSION <extension_name_3> SCHEMA <schema_name>;
CREATE EXTENSION <extension_name_4> SCHEMA <schema_name>;

  2. Use your Postgres client of choice to load the extensions. For example, using psql:

    psql <biganimal_connection_string> -f create_extensions.sql

    For more information about connecting to your cluster using a client, see Connecting to your cluster.

Working with extensions

Use the DROP EXTENSION command to remove extensions.

Use the pg_available_extensions view to see a list of all PostreSQL extensions.

The catalog_pg_extension catalog stores information about the installed extensions.
