Hi,
That's the beauty of memory contexts for small allocations. But because of the 'convenience' of memory contexts we sometimes tend to not pay attention to doing explicit pfrees. As a general rule I think allocations in TopMemoryContext should be critically examined. I was bitten by this undue bloat recently while developing some code and valgrind is not of much help in such cases because of this very beauty of memory contexts :).
Regards,

It's palloc'd in the current memory context, so it's not serious. It'll
be freed at the end of the transaction, if not before that. That's the
beauty of memory contexts; no need to worry about small allocations like
that.
Regards,
Nikhils
