No, the contents of pg_hba.conf don't directly impact the listen_addresses setting. Also, if that's where the problem is, I'd expect a failure complaining about "no pg_hba.conf entry for <connection info>". The reported "connection refused" message suggests strongly that the postmaster isn't actually listening on the desired port, which also implicates listen_addresses rather than anything else. (I think it could also be caused by a firewall filter, if the firewall is configured to send back a TCP RST rather than just drop the packet. But if "show listen_addresses" isn't showing what we expect, that's the first thing to fix.) The OP may well need to adjust pg_hba.conf too, but he's not got that far yet :-( regards, tom lane
