I took a look through this.  It seems like basically a good solution,
but the count_leaf_partitions() function is bothering me, for two
reasons:

1. It seems like a pretty expensive thing to do.  Don't we have the
info at hand somewhere already?

2. Is it really safe to do find_all_inheritors with NoLock?  If so,
a comment explaining why would be good.

            regards, tom lane
