You need to alter your indexes too. So instead of a unique index on
(say) id, you put it on (id, hostid). Then you can have colliding
ids, but it doesn't matter, because the real key is (id,hostid).
It's tricky, but you can often do it without application changes, as
long as you never do something dumb like SELECT *.
