I doubt you can blame any problems on tmpfs, here. tmpfs has been
in Solarix for many years, and has had plenty of time to stabilize.
With 768M of RAM and running only PG you not using any swap space at
all, and unix sockets don't use any appreciable space either, so the
conflicts Ian describes are impossible in your case.
