Postgresql) connection 끊기

postgresql에 커넥션이 걸리면, 끊을 수가 있다.

PostgreSQL 9.2 and above:

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'data_example' -- ← change this to your DB
  AND pid <> pg_backend_pid()
  and client_addr = '10.0.0.21'

PostgreSQL 9.1 and below:

SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'TARGET_DB' -- ← change this to your DB
  AND pid <> pg_backend_pid();

 

조회된 pid로 kill
