Обсуждение: [GENERAL] psql only works with -h (even localhost)

Hi all;


we have a client server where 'psql -h localhost' is the only way psql
will connect when ssh'd onto the db server. Would like to be able to
just run psql but not sure what the issue/fix is. Anyone have any
insight hot to fix this?


Thanks in advance

What is the error you get if you use something other then -h localhost?

What is in pg_hba.conf?

Actually, the more common case I've seen is that the server put the
socket file in directory X but psql (or more specifically libpq)
is looking in directory Y.  Try "show unix_socket_directories"
(or on older server versions "show unix_socket_directory") in a
successful connection, and compare to the path that psql shows when
bleating that it can't connect.

Usually this isn't operator error per se, but inconsistent defaults
between builds obtained from different sources.
