My concern is about this patch/capability as a whole. I agree that the
hint bit setting may be fine by itself, I'm not terribly concerned with
that. Now, if you (and others) aren't concerned about the overall
behavior that is being introduced here, that's fine, but it was my
understanding from previous discussions that making tuples visible to
all transactions, even those started before the committing transaction
which are set more strictly than 'read-committed', wasn't 'ok'.
Now, what I've honestly been hoping for on this thread was for someone
to speak up and point out why I'm wrong about this concern and explain
how this patch addresses that issue. If that's been done, I've missed
it..
Thanks,
Stephen
