Hi Folks,

It looks like the documented default for PostgreSQL's socket-directory
variable should be "/var/run/postgresql", when it's currently
"/var/lib/postgresql" (the data directory). I've attached a patch.
Here's the original commit (thanks lfam for the IRC help):

https://git.savannah.gnu.org/cgit/guix.git/commit/?id=6c0679215f4ffa534c1eb2e8c8a6e043a0c993fe

Also noticed that since a recent reconfigure, my `psql` and `createdb`
commands now need an explicit `-h /var/run/postgresql` argument to
connect to the local database where one wasn't needed before - they look
in /tmp by default.

Regards,
Ben
