Improve RLS handling in copy.c
To avoid a race condition where the relation being COPY'd could be
changed into a view or otherwise modified, keep the original lock
on the relation. Further, fully qualify the relation when building
the query up.
Also remove the poorly thought-out Assert() and check the entire
relationOids list as, post-RLS, there can certainly be multiple
relations involved and the planner does not guarantee their ordering.
Per discussion with Noah and Andres.
Back-patch to 9.5 where RLS was introduced.
