   Can confirm postgresql has the same generic typed behavior:
   
   ```
   select
   pg_typeof(sqrt(CAST('2' AS NUMERIC))),
   pg_typeof(sqrt(CAST('2' AS DOUBLE PRECISION)));
   ```
   
   Output:
   
   | pg_typeof | pg_typeof        |
   | --------- | ---------------- |
   | numeric   | double precision |
