Update query_id computation
Properly fix: - the "ONLY" in FROM [ONLY] isn't hashed - the agglevelsup field in GROUPING isn't hashed - WITH TIES not being hashed (new in PG 13) - "DISTINCT" in "GROUP BY [DISTINCT]" isn't hashed (new in PG 14) Reported-by: Julien Rouhaud Discussion: https://postgr.es/m/20210425081119.ulyzxqz23ueh3wuj@nol
