I think the reason lo_read is returning 0 is because it's not reading anything. See attached test case, cleaned up a bit from yours and with some error checks added. According to the documentation, the maximum size of a large object is 2 GB, which may be the reason for this behavior. http://www.postgresql.org/docs/9/static/lo-intro.html -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company
