Subject: pgsql: Describe special values in more GUC descriptions.
Date: Mon, 14 Sep 2026 14:16:41 +0000
Message-ID: <E1x67U9-00000000IOq-3m6y@gemulon.postgresql.org> (raw)

Describe special values in more GUC descriptions.

Commit 977d865c36 established some rules for mentioning special
values (e.g., -1, 0, an empty string) in GUC descriptions.  A few
parameters either neglect to mention their special values or
describe them in a way that doesn't follow those rules.  Most of
these parameters were added after the aforementioned commit.  This
commit fixes them.
