"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
https://github.com/Homebrew/homebrew/issues/50065 <https://github.com/Homebrew/homebrew/issues/50065&gt;

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
