   @stuartcarnie @alamb with `log` function we have some discrepancy with PG, its not brought up with this PR, it existed before
   
   ```
   ❯ select log(1, 64), log(0);
   +-------------------------+---------------+
   | log(Int64(1),Int64(64)) | log(Int64(0)) |
   +-------------------------+---------------+
   | inf                     | -inf          |
   +-------------------------+---------------+
   ```
   
   whereas PostgresSQL doesn't allow queries like that and fail the query
