PostgreSQL - relation "pg_stat_statements" does not exist

What I did:
select * from pg_stat_statements;

Error message:
ERROR:  relation "pg_stat_statements" does not exist
LINE 1: select * from pg_stat_statements
                      ^
Cause:
pg_stat_statements is not available globally but can be enabled for a specific database with CREATE EXTENSION.

Solution:
Enable pg_stat_statements:

CREATE EXTENSION pg_stat_statements;

Check it:
SELECT * FROM pg_available_extensions WHERE name = 'pg_stat_statements';
SELECT * FROM pg_available_extension_versions WHERE name = 'pg_stat_statements';
