Do you see relcreated as being something to set anew whenever the
data contents of a materialized view change due to the REFRESH
command?  I wouldn't have thought so, but I guess the problem with
that proposal is that everyone has a different idea of what the
semantics of the column would be.  Suggesting that field as the
solution here seems to reinforce that perception, anyway.
