Re: postgresql 7.3 versus 7.2

| Create a schema only dump with the 7.2 pg_dump. | Create a data only dump (possibly with INSERT output) with the 7.3| pg_dump. Assuming you haven't done anything too wacky, you should be| able to drop your 7.2 database, reload the 7.2 schema, then load up the| 7.3 data. As always, test this out before doing it on a production| system.| 

Thanks a lot for this quick explanation, this is very helpful!
By the way, is there a possibility to just do incremental
dumps/restores? Say, since a given date?
