From 1403192bb470533e48a19999f6701d7ec81741fd Mon Sep 17 00:00:00 2001 From: Melanie Plageman Date: Mon, 13 Jan 2025 10:12:27 -0500 Subject: [PATCH v1] Reorder vacuum GUCs in postgresql.conf.sample to match docs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ca9c6a5680d consolidated most of vacuum-related GUCs' documentation into a new subsection. It neglected, however, to reorganize postgresql.conf.sample to match the new order. Do this now.
