It depends. For example, currently postgreSQL allows only collation setting per
database, but somebody will develop collation per database or column. After that
the situation will be different. Upgrade have to transfer collation from control
file to catalog and so on. Configuration will be different but there will be
possible transition.
Probably all packager will delivery 8.4 and newer with integer datetime, but
people who will use in-place upgrade they will not use official package. I think
it is not good idea.
