Analyze and improve restarting Postgres (for config changes, minor upgrades)
There are several reasons to restart PostgreSQL on all nodes in the nearest future:
- upgrade to 9.6.10 gitlab-org/omnibus-gitlab#3591 (comment 93741726)
- adjust configuration https://gitlab.com/gitlab-com/production/issues/412#note_94726980
-- these changes cannot be done without restart.
This issue is created to analyze and develop ways to perform this operation with the lowest impact for users.
