Is your feature request related to a problem or challenge? Please describe what you are trying to do.
After we use subqueryAlias to replace alias in projection, we can find some optimizer rule don't support subqueryAlias.

It will cause some regression.

like #4333 (comment)

  • push_projection
  • push_limit
  • push_filter
  • .....

We need to support it, and add more UT and integration test for them.
