It does sounds a legitimate feature request to me. I don't remember if we honored the request to add resetting of cached sequences, though; if we didn't, this one is probably going to be tough too. Another point is that to implement this I think there will need to be another per-PL entry point to discard session data; are we okay with that? Since this probably means a new column in pg_language, we couldn't even consider the idea of back-patching. Unless we add a hook, which is registered in the PL's _PG_init()? Are we going to backpatch a doc change that says "releases all temporary resources, except for plptyhon's and plperl's GD"?
