Um, no, it's not quite that simple. In particular, what do you think
should happen on the client side?
I'm inclined to think that we should (continue to) have a hardwired
"primary" directory, which is the one that libpq is also configured
to look in by default. But we could add a run-time-configured list
of secondary directories to establish sockets in.
