18e4f3
Change the built-in default socket directory to be /var/run/postgresql.
18e4f3
For backwards compatibility with (probably non-libpq-based) clients that
18e4f3
might still expect to find the socket in /tmp, also create a socket in
18e4f3
/tmp.  This is to resolve communication problems with clients operating
18e4f3
under systemd's PrivateTmp environment, which won't be using the same
18e4f3
global /tmp directory as the server; see bug #825448.
18e4f3
18e4f3
Note that we apply the socket directory change at the level of the
18e4f3
hard-wired defaults in the C code, not by just twiddling the setting in
18e4f3
postgresql.conf.sample; this is so that the change will take effect on
18e4f3
server package update, without requiring any existing postgresql.conf
18e4f3
to be updated.  (Of course, a user who dislikes this behavior can still
18e4f3
override it via postgresql.conf.)
