I got this error ->
could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
Any idea to fix ,Sir?

Can you kindly explain me how to do that? Thanks Sir.

Can you tell me how to fix that? I cannot use posgresql database. Here is the error I get ->

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