Philip, the last element of the chain has caused a big problem for me changing from 7.0.2 to 7.1beta4: dumping the database out and putting back. As you might not know, at my place getting the data from the database is not a simple pg_dump, but the data come through complex filter programs (awk scripts and others). And loading the data back is also contains several scripts transforming the modified dump. So I am in a terrible need to have the same output in 7.1beta4 as in 7.0.2. I used pg_dump with -acnD and -acnd switches in 7.0.2. The old binary of pg_dump could not be used due to the changed database internals... :-( Is there any (maybe undocumented) switches satisfying my needs?
