CREATE EXTENSION

• https://www.postgresql.org/docs/current/sql-createextension.html

CREATE EXTENSION [ IF NOT EXISTS ] extension_name
   [ WITH ] [ SCHEMA schema_name ]
            [ VERSION version ]
            [ CASCADE ]

• CASCADE Automatically install any extensions that this extension depends on that are not already installed. Their dependencies are likewise automatically installed, recursively. The SCHEMA clause, if given, applies to all extensions that get installed this way. Other options of the statement are not applied to automatically-installed extensions; in particular, their default versions are always selected.

Examples

• CREATE EXTENSION pg_stat_statements;
• create extension pg_trgm;
• create extension btree_gist;
• create extension postgres_fdw;
• CREATE EXTENSION uuid-ossp;
• CREATE EXTENSION IF NOT EXISTS pg_stat_statements WITH SCHEMA public;
• CREATE EXTENSION IF NOT EXISTS timescaledb; (TimescaleDB installation)

create extension WRONG_NAME;
ERROR:  extension "wrong_name" is not available
DETAIL:  Could not open extension control file "/Users/user/brew/share/postgresql@17/extension/wrong_name.control": No such 
file or directory.
HINT:  The extension must first be installed on the system where PostgreSQL is running.
