I tried downloading the JDBC source and must say it was complex enough
to a newbie that I couldn't really determine the answer myself.    Does
anybody know if the JDBC driver with PG 8.4 communicates using a binary
protocol for BYTEA transfers to/from or whether it sends escaped chars
only?  Or perhaps which classes handle the transfer of BYTEA to PG and
receives BYTEA responses from PG?
