|
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.)
