IIRC, a hostname parameter that starts with '/' is now interpreted as
a socket path.  So you'd do psql -h /path/to/something, or set PGHOST,
to inform the client about a nonstandard socket location.

$ psql -h /nowhere -p 7654
psql: connectDBStart() -- connect() failed: No such file or directory
        Is the postmaster running locally
        and accepting connections on Unix socket '/nowhere/.s.PGSQL.7654'?
