I don't really see a need to change the protocol.  It's true that
a single tuple containing a couple dozen megabytes (per someone's
recent example) would stress the system unpleasantly, but that would
be true in a *lot* of ways.  Perhaps we should plan on keeping the
LO feature to allow for really huge objects.

As far as I've seen, 99% of users are not interested in storing objects
that are so large that handling them as single tuples would pose serious
performance problems.  It's just that a hard limit at 8K (or any other
particular small number) is annoying.
