Looks like that table has a column of type BYTEA, while the code expects it
to be a LOB. Perhaps the easiest fix is to change the table to store a LOB
instead?
One of the benefits of doing that is that you can "stream" LOB's (you access
it like a file; opening, reading, seeking), whereas AFAIK you have to
retrieve BYTEA data as a whole before you can start sending it to the
client.
