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

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 :).
