Doc: discourage use of partial indexes for poor-man's-partitioning.

Creating a bunch of non-overlapping partial indexes is generally
a bad idea, so add an example saying not to do that.

Back-patch to v10.  Before that, the alternative of using (real)
partitioning wasn't available, so that the tradeoff isn't quite
so clear cut.
