Hi all. I would like to study the protocol for large object operations (lo_read, lo_write,...) between the front-end and back-end. I've found this http://www.postgresql.org/docs/8.1/static/protocol.html, but it looks like it has no message specific for large object... How is it implemented in client (libpq, I suppose)?
