I am successfully using large objects in postgres with the latest
version of postgtres and the latest jdbc driver (thanks to a lot of help
from this list :-)) However, I need to make sure that my table is
accessible from both jdbc and odbc drivers.  I need to make sure that
programs that utilize the odbc driver for postgres can also access large
object data in the same table that the jdbc driver is accessing the

So I thought that I would have to define the large object field as type
'lo' instead of 'oid'.  But then jdbc wont recognize it.  So I tried
defining a type in the of 'lo' as VARBINARY and
also tried it as INTEGER, hoping that the driver would then recognize
the type of lo in the table but it did not work and I get the following

 Attribute 'fieldA' is of type 'lo' but expression is of type 'int4' 

Any ideas on this?  Is it possible to even do this or should I go back
to the drawing board?
