+For the RPMs, we want the custom installation directories to end in
+/pgsql not /postgresql.  This is historical but not worth changing.
+
+Notice that this patch also makes the appending of /pgsql unconditional.
+This is to avoid unexpected behavior if the RPM is built in a working
+directory whose path happens to include "postgres" or "pgsql" already.
+However, datadir and sysconfdir are already set up in the specfile's
+configure call, so we do not have to append anything to them.

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