- are transitive, while AVG, COUNT etc are not. For non-transitive aggregate functions, the re-written
- query will be incorrect.
- 3. ast has aggregates - iterate over children and add the non aggregate nodes as is and recursively get outer ast

- 4. If no aggregates, simply select its alias in outer ast.
- 5. If given ast is memorized as mentioned in the above cases, return the mapping.
