What is the best way to backup and restore large objects in the database? I don't think dump/dumpall can handle large objects or certain column types like serial. I hope there is a good way to do it such that if I upgrade to a new version of postgresql, I will be able to restore everything. I understand that tar.gzing the data directory will not work if the difference between versions changes too much. Robert B. Easter [EMAIL PROTECTED] (please cc me here, thx).
