Review Comment:
I think adjusting the rule order is probably the safest solution for now.
The current way of resolving subquery expressions is quite fragile. Ideally we
should recursively invoke the full analyzer only once (and must invoke once)
for each subquery expression, instead of doing it again and again with the `if
resolved` check.
