What resources? Most stuff (like palloc'd memory) is taken care of
for you. If you're maintaining your own private permanent data
structures then you may need to plug in a transaction-end hook
routine to clean those up.
pgsql-interfaces is hardly the place for discussing how to write
C-language server functions; if you want to discuss the fine points
I'd suggest pgsql-hackers.
