Fix memory leak created by deferrable-index-constraints patches.

Browse Source 
We need to free the OID list returned by ExecInsertIndexTuples to avoid
a query-lifespan memory leak.  When many rows require rechecking, this
can be a significant leak --- it's even more than the space used for the
queued trigger events.
