I'd start by figuring out where that packaging causes the postmaster
to write its log file, and having a look in the log file.

Hopefully there is some documentation included with the homebrew PG
package that explains that.  But if not, perhaps a look into the
launch-agent script mentioned above would tell you.  Look for something
like a -l argument to pg_ctl, or a redirection of stderr into a file.
