Several queries in the foreign_key test sort pg_constraint rows with "ORDER BY oid::regclass::text". These OIDs are constraint OIDs, not relation OIDs, so the regclass cast renders them as numeric strings, and text comparison of numeric strings depends on digit count. If the OID counter crosses a power of ten while the test runs, the output order flips, causing spurious test failures. This cannot happen in a fresh cluster, but installcheck against a long-lived cluster can hit it. To fix, sort by constraint name, which is unique within each of these queries, and use COLLATE "C" so that the order does not depend on the database's default collation either.
