Unless our docs are completely misleading I'd say that PostgreSQL is being conforming while MariaDB is treating information_schema as their version of pg_catalog (or at least our system views over top of pg_catalog). https://www.postgresql.org/docs/10/static/infoschema-tables.html If 5 and 6 and the last columns were not standard conforming it would seem pointless to include them since we don't have/implement the features they cover.
