Postpone some more stuff out of ExecInitModifyTable.
Delay creation of the projections for INSERT and UPDATE tuplesuntil they're needed. This saves a pretty fair amount of workwhen only some of the partitions are actually touched.The logic associated with identifying junk columns in UPDATE/DELETEis moved to another loop, allowing removal of one loop over thetarget relations; but it didn't actually change at all.Extracted from a larger patch, which seemed to me to be too messyto push in one commit.Amit Langote, reviewed at different times by Heikki Linnakangas andmyselfDiscussion:https://postgr.es/m/CA+HiwqG7ZruBmmih3wPsBZ4s0H2EhywrnXEduckY5Hr3fWzPWA@mail.gmail.com
