Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I installed PostgreSQL on Ubuntu, I can view psql version with command psql –version.
but when I input comman sudo -i -u postgres, it shows error:
<^>psql: 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”?<^>
