There is says:
Note: In a future release of the JDBC driver, the getBLOB() and
setBLOB() methods may no longer interact with Large Objects and will
instead work on the data type bytea. So it is recommended that you use
the LargeObject API if you intend to use Large Objects.
BTW: why don't getInputStream/getBLOB/... work for _both_, bytea and
oid? Shouldn't the JDBC driver be abled to determine the used datatype
and act accordingly? I'm sure you had you reasons. I'd just like to know
them.
