Don't worry about it now. If a plpgsql function cache entry is
discarded, we leak far more than just the function struct :-( ... and
most of it has been malloc'd, not palloc'd, so it's very hard to get
back.
Someday plpgsql should be rewritten so that it never malloc's anything,
and all its parse data structures are palloc'd into a memory context
associated with the current function cache entry. Then it would be
practical to recover the memory associated with an obsoleted cache
entry. But we've lived without this so far, so I guess it's not causing
many people problems.
