Comment (by Algunenano):

 > ST_ClusterKMeans is a thing to check (did it allocate in a loop?), also
 ST_Subdivide may requre many intermediates.

 An easy way out would be to change handlers in those functions (they are
 both changing context too) and have pfree acting as it's acting now.

 > Can we get a version of pg_free that just logs free() calls into some
 array and then frees say on 1000th free?

 I don't think that would be positive, it is the same as giving control to
 Postgres with the added complexity of handing an intermediate step
 ourselves.
