Personally I've been thinking of mounting an effort to get rid of
unnecessary pfree's wherever possible.  Particularly in user-defined
functions, "cleaning up" at the end is a waste of code space and
cycles too, because they're typically called in contexts that are
going to be reset immediately afterward.

In the case of vac_update_relstats, it's called only once per
transaction, so there's certainly no point in being a neatnik.
Stuff you need to worry about is functions that might be called
many times in the same memory context.
