From 345b2dcf070bd8fbccde643b1b2856027623e9e5 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Wed, 4 Jan 2017 13:05:29 -0500 Subject: Move partition_tuple_slot out of EState. Commit 2ac3ef7a01df859c62d0a02333b646d65eaec5ff added a TupleTapleSlot for partition tuple slot to EState (es_partition_tuple_slot) but it's more logical to have it as part of ModifyTableState (mt_partition_tuple_slot) and CopyState (partition_tuple_slot).
