So in this patch, the input restrictlist is modified to include the
clauses generated by generate_join_implied_equalities_for_all. That
doesn't seem okay -- doesn't it affect downstream usage of the
restrictlist in the caller of set_joinrel_size_estimates?
I wonder if it's possible to do this by using the ECs directly in
have_partkey_equi_join instead of using them to create fake join
clauses.
