From 3c12407f4cf735e17a8af54ab4306cd199601619 Mon Sep 17 00:00:00 2001 From: Amit Kapila Date: Tue, 21 Mar 2023 09:40:41 +0530 Subject: Ignore dropped columns during apply of update/delete. We fail to apply updates and deletes when the REPLICA IDENTITY FULL is used for the table having dropped columns. We didn't use to ignore dropped columns while doing tuple comparison among the tuples from the publisher and subscriber during apply of updates and deletes.
