Hi I've noticed tutorials for setting up MySQL but nothing for PostgreSQL. Is it possible to set PG up on DO? Also I want to launch a Rails 4 app. Are there any special instructions for that? I've never done any sys admin.! Not sure about what I need to know or where to find it, just that I'm using pg and rails

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

This is the error which i get when i tried to createuser in postgres!

Hi,

I experienced the same problem above using the Ubuntu 12.04 stack. How do I start the postgres server? Thanks!

Fixed it. The problem is with the locale and not postgres.
