I think "/var/pgsql_socket" *is* the Apple-blessed location; at least,
"strings" finds that string in /usr/lib/libpq.5.6.dylib on my Mac.
So I guess Igor is using Apple's copy of psql, or anyway a psql that is
linked to Apple's build of libpq, but the server he wishes to talk to is
using some other directory to keep the socket file in. The out-of-the-box
default directory is /tmp, but if this server was built by someone else
they might have changed that. Look around for a socket file named
".s.PGSQL.5432".

Also, you can use -h /path/to/socket/dir to specify connecting
using a socket file in a specific directory.
