ISTM that query optimization *always* works differently for inherited
versus non-inherited tables, so there are a wide variety of queries you
could describe like that.
The other problem is the documentation is sufficiently vague that it is
of little use, IMHO. Simply saying "query X is optimized differently"
without explaining what causes the difference, what the performance
impact is likely to be, or how to workaround the problem isn't likely to
be very helpful.
