Yep. Large Objects are stored (and distributed between rows) in a
specific table: `pg_largeobject'. You can use these lo records by
referencing to their OIDs. Furthermore, you cannot (also shouldn't)
reach data on pg_largeobject with another function/routine out of
supplied lo_... functions by libpq.

Yes, there's a limitation about 'em. (2GB) For more information please see:
