I was thinking about upgrading from 8.1.4 to 8.1.9. Then I will do the upgrade from 8.1.9 to 8.2.4. Is this a better approach?

You should use the following if you use large objects. pg_dump -h /host1/ -p 1234 -Fc /dbname/ | pg_restore -h /host1 -p 56789/ /dbname/// - There might be some other issues with the upgrade. I've run into permissions issues, data types that were checked more strictly, and a couple broken primary keys in my days as an admin. I'm not saying you'll run into these, but if you can, do a dry run of a dump/restore so you can solve the problems up front. Peter
