ditch the inheritance. it is no good, and makes everything too complicated
to work with.

in case you can't, do something similar to this:

select * from
(
select * from only table_a order by number desc limit 25
union
select * from only table_b order by number desc limit 25
union
select * from only table_c order by number desc limit 25
) x
order by number desc limit 25;

it should be faster. and yes, i know it's ugly.
