    allpaths.c:find_join_paths(): compute_rel_size() shouldn't be called · 11073bee

    for join-relations. Sizes already computed by
prune_rel_paths():compute_joinrel_size().

joinrels.c:
<                   if ( _use_right_sided_plans_ )

 - r_plans are useful when outer_rel is join-relation... It
decreases the size of search space...
