Can't Start Server

Hi folks.

I just installed postgresql(at)12 onto MacOS Big Sur. It won’t start. The postgres user is not created, and the setup is new to me with regards to homebrew’s relocation into its own opt/ directory. I’ve set up postgresql.conf and pg_hba.conf like my old setup, so things should be good. I just can’t get it to start up.

Anybody have any insight into this? I appreciate any leadership.

/opt/homebrew/var/postgresql(at)12 stable ❯ pg_ctl -D opt/homebrew/opt/postgresql(at)12/bin/postgres start
pg_ctl: could not open PID file "/opt/homebrew/opt/postgresql(at)12/bin/postgres/postmaster.pid": Not a directory

/opt/homebrew/var/postgresql(at)12 stable ❯ brew services list

~ ❯ sudo su - postgres

~ ❯ brew services start postgresql(at)12
