Subject: pgsql: Special case C_COLLATION_OID in pg_newlocale_from_collation().
Date: Wed, 05 Nov 2025 00:49:41 +0000
Message-ID: <E1vGRiX-0054Xx-2F@gemulon.postgresql.org> (raw)
Special case C_COLLATION_OID in pg_newlocale_from_collation().
Allow pg_newlocale_from_collation(C_COLLATION_OID) to work even if
there's no catalog access, which some extensions expect.
Not known to be a bug without extensions involved, but backport to 18.
Also corrects an issue in master with dummy_c_locale (introduced in
commit 5a38104b36) where deterministic was not set. That wasn't a bug,
but could have been if that structure was used more widely.
