So, what's different between your table declaration and my toy example?
Can you force it to use the partial index by dropping the other index?
(Use begin; drop index ...; explain ...; rollback; to avoid dropping
the index for real.) It's quite unclear at this point whether it
believes it *cannot* use the partial index, or whether it just thinks
the other index is cheaper.
