You can, but it's pretty backward.  If you Java you'd probably be better
off using it to slurp in the file and do the insert there.  If you
really want to use large objects to go to byteas have a look through the
client side API[1] and then at the functions available to call from SQL
by doing \df from psql as they mirror the client calls very closely.

Be aware that you'll be creating a lot more "garbage" that PG will have
to clean out, so importing many gigabytes of data this way will take
much longer.
