How can I investigate this? > it's on 5433: Hmm, something odd there, because a port number mismatch should have resulted in psql failing to connect via unix socket either. Maybe you have more than one active postmaster? Anyway, given these settings, "psql -p 5433 -h localhost" should connect. If you still get "connection refused" then you need to look at the kernel firewall (packet filter) settings. regards, tom lane
