pg_stat_statements enabled, but the table does not exist
Extension isn't installed:
SELECT *
FROM pg_available_extensions
WHERE
name = 'pg_stat_statements' and
installed_version is not null;
If the table is empty, create the extension:
CREATE EXTENSION pg_stat_statements;
I've faced with this issue at configuring Percona Monitoring and Management (PMM) because by some strange reason PMM connecting to database with name postgres
, so pg_stat_statements
extension have to be created in this database:
yourdb# \c postgres
postgres# CREATE EXTENSION pg_stat_statements SCHEMA public;
Follow below steps:
Create the extension
CREATE EXTENSION pg_stat_statements;
Change in config
alter system set shared_preload_libraries='pg_stat_statements';
Restart
$ systemctl restart postgresql
Verify changes applied or not.
select * from pg_file_Settings where name='shared_preload_libraries';
The applied attribute must be 'true'.
