The config file: #{etc}/pgbouncer.ini is in the "ini" format and you
will need to edit it for your particular setup. See:
http://pgbouncer.projects.postgresql.org/doc/config.html

The auth_file option should point to the #{etc}/userlist.txt file which
can be populated by the #{bin}/mkauth.py script.

If this is your first install, automatically load on login with:
    mkdir -p ~/Library/LaunchAgents
    cp #{plist_path} ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

If this is an upgrade and you already have the #{plist_path.basename}
loaded:
    launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
    cp #{plist_path} ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

Or start manually with:
    pgbouncer -q #{etc}/pgbouncer.ini
    EOS
