From 4dad3cf6aefb813bb3bd1f4b2fed3c801a608b95 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Tue, 8 Nov 2022 09:57:30 +0900 Subject: [PATCH v17 3/3] Allow file inclusion in pg_hba and pg_ident files. pg_hba.conf file now has support for "include", "include_dir" and "include_if_exists" directives, which work similarly to the same directives in the postgresql.conf file. This fixes a possible crash if a secondary file tries to include itself as there's now a nesting depth check in the inclusion code path, same as the postgresql.conf. Many regression tests added to cover both the new directives, but also error detection for the whole pg_hba / pg_ident files. Catversion is bumped.
