Can't access Brew PostgreSQL
Seems like the file was not read properly.


make sure that you restarted the postgresql-server after editing the file
make really sure that it's restarted (I ran into this twice...)
try again.


I searched one day for one suche error and a simple restart was all that was needed.

Also: with the last homebrew-install I made, my current user was setup automatically without password. so I could just execute psql template0 and was connected to the server.

From there, you can create databases, roles and so on.
