You don't need the alias; "SELECT pg_class FROM pg_class" generates
the same behavior.
Looks to me like the parser is failing to reject this query as malformed.
transformIdent() is willing to take either a column name or a relation
name (why?), and no one upstream is rejecting the relation-name case.
End result is an untransformed Ident node gets left in the parser
output, and neither the rewriter nor the planner know what to do with
it.
