* NOTES
* this is the "main" module of the postgres backend and
* trees. The present (bizarre) implementation of UNION/INTERSECT/EXCEPT
* doesn't run analysis of the second and later subqueries until rewrite,
* so we'd get false failures on these queries if we did it beforehand.
- *
- * Currently, copyObject doesn't know about most of the utility query
- * types, so suppress the check until that can be fixed... it should
- * be fixed, though.
