These are instructions to setup Postgres.app to allow connections over unix sockets. These instructions were written for macOS Sierra (10.12) and Postgres.app 9.6.0

1. Run Postgres.app once so that the configuration is initialized in ~/Library/Application Support/Postgres/var-9.6/
2. Quit Postgres.app
3. Open ~/Library/Application Support/Postgres/var-9.6/postgresql.conf in your favorite text editor
4. Uncomment the line unix_socket_directories = '/tmp' and change it to unix_socket_directories = '/var/pgsql_socket,/tmp'
5. Run sudo mkdir -p /var/pgsql_socket
6. Run sudo chmod 770 /var/pgsql_socket
7. Run sudo chown root:staff /var/pgsql_socket
