It wasn't different in the past (only there's no available documentation for
versions before 6.0 to check), but could surely be different in the future.

BTW, I've never asked to delete the directions to go to the URL!

The back up/restore process is not necessary at every FC upgrade, since major
versions of PostgreSQL are released every 10-13 months. So in any case we need
to check the validity of the actual version of the statement.

Ok, but to me it's still not clear that you have to back up _before_ upgrading
Fedora, so I'll try anyway to suggest an enhancement, please consider it and let
me know. Substitute this:

"Fedora Core 4 provided version 8.0 of PostgreSQL. If you upgrade an existing
Fedora system with a PostgreSQL database, you must upgrade the database to
access the data.
To upgrade a database from a previous version of PostgreSQL, follow the
procedure described at
http://www.postgresql.org/docs/8.1/interactive/install-upgrading.html.";

with:

"Before upgrading an existing Fedora Core system with a PostgreSQL database, it
could be necessary to follow the procedure described at
http://www.postgresql.org/docs/8.1/interactive/install-upgrading.html. Otherwise
the data may be not accessible by the new version of PostgreSQL."

My sentence works for all the previous versions of FC/PgSQL and works also if
the internal data format hasn't changed. Only the URL must be updated for new FC
releases.
