"brew services list" shows postgresql as "started", but can not connect to it

Hello!

I am trying to move from (successfully) using VM Fusion with CentOS Linux image on Mac OSX "El Capitan" for web development to Homebrew:

    brew update
    brew install postgres
    brew tap homebrew/services

This resulted in some files installed to

   /usr/local/Cellar/postgresql/9.5.1/

And "brew services list" reports it as "started":

    postgresql started afarber /Users/afarber/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

And I can restart it:

    # brew services restart postgresql
    Stopping `postgresql`... (might take a while)
    ==> Successfully stopped `postgresql` (label: homebrew.mxcl.postgresql)
    ==> Successfully started `postgresql` (label: homebrew.mxcl.postgresql)

But unfortunately I can not connect with "psql":

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

And there is no "pg", "post" or "master" in "ps uawwwx" list.

And I can find neither postgresql.conf nor pg_hba.conf nor any startup logs at my Macbook Air.

In the troubleshooting process I have tried:

    xcode-select --install
    brew update
    brew update
    sudo chown -R $(whoami) $(brew --prefix)

and restarted the Macbook and finally filed an issue at

If you are using Homebrew PostgreSQL package at the latest Mac OSX, please share some tips on how to get it running or at least proceed in debugging.

Thank you
Alex

Did you initialize the DB cluster (initdb -D /path/to/data)?
Did you configure the installation (postgres.conf file)?
Does homebrew.mxcl.postgresql where the data lives?

when you run "ps -ef|grep -i postg", do you see the postmaster and other postgres executables running?

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.
