Gentoo, 8,2 ---> 8.4, and /var/run/postgresql in mode 770

I just upgraded my home gentoo system's postgresql from 8.2.14 to
8.4.2.  I use it mostly for fooling around and keeping smatterings of
personal data, so it was simple laziness which kept me from upgrading
sooner, triggered by the gentoo switch back in 8.2.mumble in how they
manage postgresql.

Everything went smoothly except the permissions of the directory
/var/run/postgresql with the domain socket .s.PGSQL.5432.  This dir
had permissions of 770, owned by postgres.postgres, so no mere mortals
could access it.  I have changed this to 775 and can now access it.

Didn't 8.2 put these in /tmp?  Maybe this was a gentoo thing.  What
should the permissions be for this?  Or does gentoo do their own thing
and there is a different "standard" way of handling this?
