Thread: pgsql: Update wording in optimizer/README for EquivalenceClasses
Update wording in optimizer/README for EquivalenceClasses d69d45a5a changed how em_is_child members are stored in EquivalenceClasses. Children are no longer stored in the ec_members list. optimizer/README mentioned that most operations "should ignore child members", but that felt a little untrue now since child members are now stored in a separate place, they simply won't be found by the normal means of looking (a foreach loop over ec_members), and if you don't find them, there's technically no need to "ignore" them. Here we tweak the wording slightly to reflect the new storage location for child members.
