From d69d01ba9d8d774487032459ebb83d2086715f01 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 5 Dec 2022 12:36:40 -0500 Subject: Fix Memoize to work with partitionwise joining. A couple of places weren't up to speed for this. By sheer good luck, we didn't fail but just selected a non-memoized join plan, at least in the test case we have. Nonetheless, it's a bug, and I'm not quite sure that it couldn't have worse consequences in other examples. So back-patch to v14 where Memoize came in.
