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... Dmitry Tkach
PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions.
