Comment (by Simon Charette):
> it looks like the code will not work at all with MariaDB with
ONLY_FULL_GROUP_BY turned on.
That's good to know thanks for investigating further that's appreciated! I
think it's worth having a separate ticket for it yes. The solution will
likely be to turn off the `allows_group_by_selected_pks` feature on
MariaDB when `ONLY_FULL_GROUP_BY` mode is turned on. Note that the
`allows_group_by_selected_pks` feature is different from the
`allows_group_by_pk` feature removed in
041551d716b69ee7c81199eee86a2d10a72e15ab.
