The analysis of a with clause should have its own global state so the local view(s) can be analyzed without polluting the global state of the parent QueryStmt. This might not always matter, but in a complex query involving a with clause that contained a subquery, re-analysis of the WithClause after the subquery rewrite resulted in an invalid Exists conjunct being registered in the parent analyzer's global state. The Exists conjunct was assigned to a scan node which then failed a pre-condition check.
