OK. If I got you right, the Postgres JDBC driver "simulates" the
java.sql.Blob
getBinaryStream() etc. methods by using LargeObject internally.
That seems to be a working solution for me. I just want to keep my
application's
database layer compatible using ordinary JDBC objects. I don't mind if
they are mapped to LargeObject internally. Actually that's even better
regarding
the streaming issues :-)
I assume that I can use this to read and write Blobs, not to delete them
since the LargeObject wouldn't be unlinked.
I'm not familiar with the JDBC driver source, and I would be glad if you
could
confirm this just one more time.

It certainly works with Postgres, the only question is if it works with
blobs?
I'll try it out.
Thanks for your help,
