From 49a1c22889d428558c8e5accb55afa538ef0ca3f Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 16 Oct 2018 13:56:58 -0400 Subject: [PATCH] Avoid rare race condition in privileges.sql regression test. We created a temp table, then switched to a new session, leaving the old session to clean up its temp objects in background. If that took long enough, the eventual attempt to drop the user that owns the temp table could fail, as exhibited today by sidewinder. Fix by dropping the temp table explicitly when we're done with it. It's been like this for quite some time, so back-patch to all supported branches.
