Gitlab 14.2.1, issue with external postgres

Hello, forgive me for my bad english.

I’ve upgraded my GitLab instance from 14.1.0-ee to 14.2.1-ee, and since this upgrade randomly the users have some errors (500, 404, etc). After investigation, it seems that all connections to my separate postgres database are full:

FATAL: remaining connection slots are reserved for non-replication superuser connections

It seems that the 14.2.1 version makes a lot more connections to postgres or does not release unused connections ?

Actually I have updated postgres max_connections to 200 (100 to 200). But I really don’t know if it is a real solution.

  • Gtlab 14.2.1-ee on docker
  • Postgres 12.3 on docker

Some outputs from postgres:

root@0b4b4644e1b3:/var/lib/postgresql# psql -U gitlab -d gitlab
psql (12.3 (Ubuntu 12.3-1.pgdg18.04+1))
Type "help" for help.
