Statistics Module seems to rely on MySQL only facility

The statistics module seems to be relying on the MySQL facility whereby a column in a SELECT list, not referenced in a GROUP BY clause outputs the last value seen for that column within the groupings of the other fields. Postgres does not have this facility and instead rejects the query as invalid SQL.

Therefore, the select clauses which are retrieving the data for the individual sub pages under admin/log/hits all fail in Postgres.
