PosrgreSQL 7.0.x has a compiletime tuplesize limit which is by default
8kb. This limitation doesn't exist in the 7.1 version, so I would suggest
getting it from ftp://ftp.postgresql.org/pub/dev/. It is still RC2, but
I think it can already be used in noncritical enviroments. Using large
objects is not a very good idea, because it is imho very cumbersome
in this case.
