Subject: pgsql: Add test case for same-type reordered FK columns
Date: Fri, 10 Apr 2026 09:12:37 +0000
Message-ID: <E1wB7un-000HHt-0T@gemulon.postgresql.org> (raw)
Add test case for same-type reordered FK columns
The test added in 980c1a85d819 covered reordered FK columns with
different types, which triggered an "operator not a member of opfamily"
error in the fast-path prior to that commit. Add a test for the
same-type case, which is also fixed by that commit but where the wrong
scan key ordering instead produced a spurious FK violation without any
internal error.
