Socket File “/var/pgsql_socket/.s.PGSQL.5432” Missing In Mountain Lion (OS X Server)

Question

I just upgraded my MacMini Server from Lion Server to Mountain Lion using OS X Server. I am having the same problem with PostgreSQL that I did last year when I first instal

Answer 1

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

I kept on getting the above error and none of the above solutions worked for me. Finally the following solution solved my problem on Mac OS X

Install postgres using brew

brew install postgres

Install brew services

brew tap homebrew/services

To start postgres as a background service

brew services start postgresql

To stop postgres manually

brew services stop postgresql

We can also use brew services to restart Postgres

brew services restart postgresql
