Multiple postgres processes running that can't be quit & could not start on port 5432.

I originally downloaded Postgres with Postgres.app, deleted it from the Applications folder and then downloaded with homebrew, since then I keep getting the could not start on port 5432 error even after deleting ~/Library/Application Support/Postgres, and I have 7 postgres processes that can't be force quit.

• try uninstalling the homebrew version using brew remove postgresql
• restart your computer
• check in activity monitor to make sure no more postgres processes are around
• open Postgres.app again

(Hint: To kill postgres, try killing the process with the lowest PID. The others are child processes that will be respawned by the parent process.)

that seemed to work, thanks! I have two postgres applications listed now (Postgres and Postgres-9.3.5.0), is there one that I can safely delete or should I just leave them be?

That's probably two copies of the same app, check in get info. Just delete "Postgres-9.3.5.0"
