Join the Slony project? Seriously, this is one of the uses of slony. All
you'd need would be a script that would:
1) Install PG 8.0 to an alternate directory;
2) Start 8.0;
3) install Slony on both instances (the 7.4 and the 8.0);
4) make 7.4 the "master" and start replicating
5) when 8.0 is caught up, stop 7.4 and promote it to Master
6) turn off Slony.
