number of pg_ctl processes keep increasing on macos High Sierra

[idkwa]

After approximately one day of system uptime, my MacBook Pro runs extremely slow. I am running macOS 10.13.5 and Activity Monitor shows ~70% idle cpu usage and the memory pressure is on green but there are what seems like thousands of pg_ctl processes running by the user _teamsserver. With a restart, the number of processes slowly increase back to a large number and slows the computer again. Activity monitor shows the number of processes to be ~2100.

How can I determine what the _teamsserver and pg_ctl are so I disable them or what's launching these?

pg_ctl seems to be the PostgreSQL database. teamsserver seems to be used by the wiki server and/or otherwise comes with the macOS Server app. It looks like PostgreSQL is also part of the macOS Server app. It might show up as Server.app in your applications folder. These programs would not have been installed as part of the regular OS install. If none of this sounds familiar, you need to get a listing of what programs are starting up automatically.

This is for Sierra, but the same applies for High Sierra.

If there is nothing there that doesn't seem to match teamsserver or PostgreSQL or a wiki server, then you need to look at startup items not associated with your ID. I would suggest installing EtreCheck and running a report. You can look at the report and see what startup items there are. EtreCheck is frequently recommended on these forums - it's safe if it's downloaded from their website and the reports they produce removes user-specific data. However, I just downloaded it today for some work I needed to and see they have a new version out which takes several minutes to run (older version was faster) because I think it's running performance benchmarks. It's also now has 5 free trials (previously it was totally free). Once run, you need to go to the "Report" tab on the left and you look under "Launch Agents" and go through the sections from there until User Login Items and see if you recognize a program that could be running teamserver and PostgreSQL. If you don't see anything, you should post the report here.
