In the case of MS SQL Server the issue doesn't come up.  Here are some
user experiences:

1) Create a database in MS SS 6
2) Upgrade software to MS SS 7
3) Use software


1) Create a database in MS SS 6
2) Backup database (closest analog is -Fc option of pg_dump)
3) Move backup to machine running MS SS 7
4) Attempt to restore.  Program warns it will upgrade database and you
can't go back, proceed?  You say yes.
