From 0b717432ff13683f9d13f007dab1c3380cae2f0d Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Tue, 17 Jan 2023 13:41:09 +0900 Subject: Track behavior of \1 in pg_ident.conf when quoted Entries of pg-user in pg_ident.conf that are quoted and include '\1' allow a replacement from a subexpression in a system user regexp. This commit adds a test to track this behavior and a note in the documentation, as it could be affected by the use of an AuthToken for the pg-user in the IdentLines parsed. This subject has come up in the discussion aimed at extending the support of pg-user in ident entries for more patterns.
