Here's a first attempt at doing that. I vote to backpatch this to pg11
(since this functionality is all there).

Sure, just "alter table only parent", without explicitly marking it not
valid. Then the indexes on children must be attached to the parent
indexes; this searches for constraints and does the right thing.

In the end, it seemed material far too short to have its own subsection,
but maybe if we redesign the whole section we could lay it out
differently? (One idea would be to leave 5.11 for declarative
partitioning, and add a new section 5.12 for legacy inheritance.
Something to think about for pg13)
