As a general point, it would probably be a good idea to address each
of these issues separately, and to have a separate discussion about
each one.
As to #1 specifically, if you use a text or bytea field rather than a
large object per se, then this issue goes away. But then you lose the
streaming functionality. So at least some people here are saying that
we should try to fix that by adding the streaming functionality to
text/bytea rather than by doing anything to the large object facility.
