Do we need to add another CCI after reindexing the TOAST table? It looks
like we presently do so between reindexing each relation, including the
TOAST table.

I'm not following this. We've already obtained the list of index OIDs
before this point. Does this create problems when we try to open and lock
the relations? And if so, how?
