Peter,

> What difference would pg_dump make?

For many user's databases ... many more than any previous version after 
7.3 ... using the old version's pg_dump *will not load* into 8.3.  Unless you 
restore the casts.

Right.  We've talked (on IRC) about putting together a package which restores 
the removed casts.

Given that Gentoo, Red Hat and SuSE don't support having multiple PostgreSQL 
versions on the system in their packaging, I'm thinking the "restore casts" 
package is essential rather than being a nice idea.

Should I be discussing this on a different list?
