No, we shouldn't, and if I had any authority over them I would make
Debian stop doing that.  It amounts to a unilateral distro-specific
change in the protocol, and I think it makes things *less* secure,
because any clients who are expecting the socket to be in /tmp will be
easy pickings for a spoofer.  Debian cannot hope to prevent that
scenario, because there are non-libpq-based client implementations.
