Brad Jorsch c394cdc04d API: Avoid MySQL filesort with list=allpages&apfilterlanglinks=withlanglinks 
I'm not sure whether r44584 didn't go far enough or if MySQL's behavior
has changed since 2008, but MySQL is now filesorting when a
constant-in-WHERE field is included in GROUP BY.

If all our supported databases used the 1999 SQL standard rules for
GROUP BY[1] this would be an easy fix. But PostgreSQL before 9.1 uses
the older 1992 rules.[2] And then there's Oracle and MSSQL, which aren't
listed as supported[1] but are still in the code. Simplest thing to do
is probably to check if we're on MySQL, Sqlite, or Postgres >= 9.1 and
use the 1999 rules, and otherwise use the older rules.

 [1]: Basically "any non-aggregate field in the SELECT must be
      functionally dependent on the grouped-by fields", meaning if you
      include the primary key you're good.
 [2]: Basically "any non-aggregate field in the SELECT must be in the
      GROUP BY".
