I did:

stop the postmaster (7.4.x)
mv /usr/local/pgsql /usr/local/pgsql7.4.x
install pg 8.0.0 as usual
restart postmaster with -D /usr/local/pgsql7.4.x/data
pg_dumpall > db.out
#if your path is set as before and 8.0.0 is installed in
/usr/local/pgsql, pg_dumpall is now the 8.0.0 version
stop the postmaster with -D /usr/local/pgsql7.4.x/data
start the postmaster with -D /usr/local/pgsql/data
restore the database as usual.

This worked for me.
