From 9be95ef156e7c2ae0924300acddd483504fa33b3 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 9 Nov 2017 11:30:30 -0500 Subject: [PATCH] Fix bogus logic for checking executables' versions within pg_upgrade. Somebody messed up a refactoring here. As it stood, we'd check pg_ctl's --version output twice for each cluster. Worse, the first check for the new cluster's version happened before we'd done any validate_exec checks there, breaking the check ordering the code intended. A.
