Re: Postgresql upgrade from 8.4 to latest

But what I read, in-place upgrade has smaller outage, compared to
dump/restore. But so many articles on having bugs afterwards.
Do you think it is a good idea to use pg_upgrade for critical database
application?
Or any other tool should I consider? For example - slony?

Thanks for advice.
Regards.
