In particular, it looks like the list of groups you belong to is
typically only computed at login time (or equivalently su -l, which
is what's happening in the postgres init script), and then just
inherited by all processes launched from that login. So there is
caching of a sort going on here, but it's in the kernel and there's
nothing we can do about it.
