It's been enabled by some services already, including Apache, while PostgreSQL uses system's /tmp directory, where its unix socket is located. Naturally, it resulted in a state, where Apache or other services with PrivateTmp enabled are not able to communicate with PostgreSQL using the socket.
Couldn't you simply tell postgres to put it's socket in, say, /var/run, and create a symlink to that socket in the global /tmp directory?

A question I'd like to ask now is: Do we need a new configuration variable for this or it's enough to have the location hard-coded? What are your opinions?
If we're going to have this at all, we should go all the way and support an arbitrary number of sockets. But then, is there any advantage in providing this feature natively compare to simply creating symlinks?
