PostgreSQL: Why psql can't connect to server?

Question

I typed psql and I get this:

psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    con         


        

Answer 1

Restarting the instance worked for me. Also, as mentioned in some other post psql -h '/tmp' worked as well before the restart. But post restart psql directly started working. So, probably some file ownership issues that got reset with the restart is what I am thinking.
