Hi!
I have PostgreSQL 7.4 DBM and want to upgrade to 8.2 (latest in version 8 I quess).

Can use the DATADIR from 7.4 and just upgrade the DBM/postgresql server to 8.2?

Is the upgrade from 7 to 8 procedure written down somewhere? (could not find anyting at http://www.postgresql.org/docs/techdocs.2, except from 6 to 7)

I guess I could dump all my data and restore it later but it would be much nicer if it was possible to just start a new PostgreSQL server with the old DATADIR repository!

Thanks!

/Rick
