It seems that ExecInit/EndIndexScan is leaking some memory...

Browse Source 
For example, if I run a query, that uses an index scan, and call
MemoryContextSt ats (CurrentMemoryContext) before ExecutorStart() and
after ExecutorEnd() in ProcessQuery(), I am consistently see ing that
the 'after' call shows 256 bytes more used, then 'before'...

The problem seems to be in ExecEndIndexScan - it does not release
scanstate, ind exstate, indexstate->iss_RelationDescs and indexstate ->
iss_ScanDescs...
