plpgsql doesn't allow access to shared memory now. You can use plper
for caching some resuts. I am not sure if result cache is generally
accaptable technique, but I thing, I can write similar functionality
for orafce
if you need anything hurry, use plperl
http://www.postgresql.org/docs/8.2/interactive/plperl-global.html and
$_SHARED array.
