From a1115fa0782378a8238045d238ae70cac36be8ae Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 6 Apr 2021 18:13:05 -0400 Subject: Postpone some more stuff out of ExecInitModifyTable. Delay creation of the projections for INSERT and UPDATE tuples until they're needed. This saves a pretty fair amount of work when only some of the partitions are actually touched. The logic associated with identifying junk columns in UPDATE/DELETE is moved to another loop, allowing removal of one loop over the target relations; but it didn't actually change at all. Extracted from a larger patch, which seemed to me to be too messy to push in one commit.
