I just looked through the manual but could not find an "oid data type".
I thought that oids were some kind of unique row "address" (at least
that's what http://www.postgresql.org/docs/8.2/static/datatype-oid.html
sates as far as I can tell)

Can you point me to the manual for these types of BLOBs are described?
The "Data Types" chapter does not list them as far as I can tell.

Background: I'm maintaining a SQL front end (Java/JDBC based) which
supports reading and writing of BLOBs and I would like to make sure that
I also support these "oid data type" BLOBs
