From c3ec4f8fe867807613c08fe16789434ab1a74a15 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 7 Nov 2021 12:18:18 -0500 Subject: [PATCH] Silence uninitialized-variable warning. Quite a few buildfarm animals are warning about this, and lapwing is actually failing (because -Werror). It's a false positive AFAICS, so no need to do more than zero the variable to start with.
