Обсуждение: rtree memory leak patch

Here is a patch for a memory leak in rtree.c, version 7.2.1 (in code
that I submitted last year, alas).

PointerGetDatum(&size_alpha));
                         FunctionCall2(&rtstate->sizeFn, union_dr,

PointerGetDatum(&size_beta));
+                       pfree(DatumGetPointer(union_dl));
+                       pfree(DatumGetPointer(union_dr));

                         diff = (size_alpha - size_l) - (size_beta -
size_r);

Your patch has been added to the PostgreSQL unapplied patches list at:

I will try to apply it within the next 48 hours.
