"optimization".  When we find a potentially useful joinclause, we
have to add all its other required_relids to the result, not only the
other clause_relids.  They are different in the case of a joinclause
whose applicability has to be postponed due to outer join.  We have
to include the extra rels because otherwise, after best_inner_indexscan
masks the join rels with index_outer_relids, it will always fail to
find the joinclause as applicable.  Per report from Husam Tomeh.

in which invalid page data could be transiently written to disk by
concurrent bgwriter activity.  There doesn't seem any risk of loss of
actual user data, but an empty page could possibly be left corrupt if a
crash occurs before the correct data gets written out.  Pointed out by
Alvaro Herrera.

It uses existing macros instead of touching directly.

we'd better make it work like this.
