From f00da6d841ad3a506aaa7b8d532fd7b5a4a8f247 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Sun, 30 Sep 2001 20:16:21 +0000
Subject: Allow the postmaster to accept changes in PGC_BACKEND GUC variables
 from the config file, so that these changes will propagate to backends
 started later.  Already-started backends continue to ignore changes in these
 variables.
