I don't have anything to add to what others said already. Your best 
advice is to test it yourself.

I would expect the plan time to be linear relative to the number of 
partial indexes or child tables involved, except that constraint 
exclusion of CHECK constraints on the partitions is exponential. But I 
also wouldn't be surprised if there's some other non-linear aspect there 
that shows its head with thousands of partitions.
