Thread: pgsql: Avoid creating a RESULT RTE that's marked LATERAL.
Avoid creating a RESULT RTE that's marked LATERAL. Commit 7266d0997 added code to pull up simple constant function results, converting the RTE_FUNCTION RTE to a dummy RTE_RESULT RTE since it no longer need be scanned. But I forgot to clear the LATERAL flag if the RTE has it set. If the function reduced to a constant, it surely contains no lateral references so this simplification is logically OK. It's needed because various other places will Assert that RESULT RTEs aren't LATERAL. Per bug #17097 from Yaoguang Chen. Back-patch to v13 where the faulty code came in.
