As you know, PostgreSQL has a large objects facility [1]. I'm curious are there real systems which are use this feature? I'm asking because and I'm in doubt should the Pgfe driver [2] provide the convenient API for working with large objects or not. Thanks! Yea, we use LOs, because using JDBC bytea reallys doesn't stream (at least using the pgjdbc-ng driver). When retrieving bytea using JDBC it retunrs an InputStream but it's backed by an in-memory byte[]. With LOs and java.sql.Blob (which the standard pgjdbc-dirver doesn't support ,but pgjdbc-ngdoes) it acutally uses strams and memory is kept down to a minimum. -- Andreas Joseph Krogh
