Hello, In DBD::Pg one can read (line 134): $lobj_fd = $dbh->func($lobjId, $mode, 'lo_open'); But how is the LOB retrieved in the first place? If I pass the OID of an existing LOB instance from a table the returned $lobj_fd is null. What kind of $lobjId is one supposed to pass to this function to open a LOB? The aim is to be able to read a LOB from a postgres DB without having to lo_export the object to a file first. Can that be done with the $dbh->func() interface? (using lo_open, lo_read, etc ..)
