Dear Mark,
When you specify server name with -h parameter, psql uses TCP socket to connect PostgreSQL server. Due to being changed default unix socket directory, you should give socket directory path with -h parameter to psql if you want to create connection via Unix socket. Please try following parameters.
psql -p 5433 -h /database/prime_data/PSQL_94/tmp -U postgres prime_production
Best regards.
İyi çalışmalar.

Good morning,I run a postgres 9.4.8 standby server, replicating our production server. I can login using our pguser linux login if I specify the host on the command line but cannot login if I leave the host off:psql -U postgres prime_production -p 5433 -h arprodpsqlreplication01Password for user postgres:psql (9.4.8)Type "help" for help.psql -U postgres prime_production -p 5433psql: could not connect to server: No such file or directoryIs the server running locally and acceptingconnections on Unix domain socket "/tmp/.s.PGSQL.5433"?I have changed the UNIX_SOCKET_DIRECTORIES to something other than /tmp because we have another instance pointing to that directory. I restarted postgres. Didn't help. I have attached our 3 config files along with an ls -la listing of our database cluster directory. Any insights welcome.Thank you--Mark Steben
