could not connect to database postgres
I'm trying to install postgresql but I'm running into an error when I try to create a user:
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"?
It sounds like postgres isn't running. There is a ton of information on managing it from here https://help.ubuntu.com/community/PostgreSQL
Peter, is this in development or in production? If it's Linux and your on production you can do a
service postgresql status to see if it it's running or a
ps aux | grep -i post to see if there are any Postgres processes running.
