No it says you are using the 9.4.5 version of psql to connect to a 9.3.4
server. psql is available independent of the server running. You will
need to see if both servers are running by doing something like:
ps ax | grep postgres

Before you do any of that you need to verify that the servers you want
are running. Remember they can not share a port, so you need to look at
what the port settings are in the respective postgresql.conf files.
