But EState's not it.
Well, I discover there is an allocation of 8232 (inflation...) made once per statement by a memory context called... ExecutorState. Still not sure exactly which allocation this is, but its definitely once per statement on pgbench, which should narrow it down. Plan, query etc? I don't see a way to hack the allocation, since the max chunk size is 8K. -- Simon Riggs EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
