Even though I've tried it in about a thousand different versions it doesn't seem to work right. The documentation in Manual Section 7 is rather poor and the Example doesn't work either. The closest I could get was that the some writing access was done to "pg_largre_object" but the attemt to read it out failed. A frequent error message was after the command: inv_fd = p_open("/inv_file2", INV_WRITE, Inversion); Error: Unexpected identifier: ? so before I describe the whole mess in more detail: 1. Does anybody have experience with large objects who can explain the access via LIBPQ or via the monitor. 2. Can anybody send me some example-programms for storing data in large objects (in Unix as well as in in Inversion files).
