After updating to 0.19.5 from 0.19.3 my postgres is often using up 500%+ of CPU according to docker stats and often going to 100% CPU on most cores according to htop. Also noticed in the uptime monitor:

htop shows one of the 5 postgres processes constantly on UPDATE. I think this might be part of the problem.

I’m not comfortable with postgres and am honestly completely in the dark how or where to mitigate or even pinpoint this issue.

Any help would be appreciated.

      I added pg_stat_statements, and ran it. This was the result:

      # SELECT count(*) FROM pg_stat_activity;
       count
      -------
          11
      (1 row)

        do you also have pict-rs connected to this postgres instance? that is surprisingly low number to me, I would have expected anywhere between 20-50 active connections (I use 50 for lemmy and 20 for pict-rs, configured in their respective conf files)
