postgresql – To Kill postgresql Sessions for a specific database

Sometimes it is necessary for the database administrator to remove existing connected sessions. For example to drop a database when users and/or applications cannot (or will not) disconnect or terminate cleanly.

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'database_name_with_existing_sessions'
AND pid <> pg_backend_pid();
