But only if you use large objects.
From my perspective bytea is the (only) data type that matches the JDBC BLOB type.
And none of the problems you have occur when using bytea.
There is no match for PG's large objects in the JDBC API so I don't see your claim that it's a fault of the driver.
What's the reason for you to stick with LargeObjects?
