I'm not thrilled with that; it's totally insecure on platforms where /tmp
isn't "sticky", so it doesn't seem like an appropriate solution given
that this discussion is now being driven by security concerns.


I re-read that thread.  While we did fix the reporting end of it, ie
the postmaster will now give you a clear failure message if your
socket path is too long, that's going to be cold comfort to anyone
who has to build in an environment they don't have much control over
(such as my still-hypothetical-I-hope scenario about Red Hat package

I'm inclined to suggest that we should put the socket under $CWD by
default, but provide some way for the user to override that choice.
If they want to put it in /tmp, it's on their head as to how secure
that is.  On most modern platforms it'd be fine.
