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.

Hi,

I need to upgrade Postgresql database from 8.4 to latest stable version
(9.4). The db size is almost 2.5 TB.
Is pg_upgrade in-place is a good idea for it?

 With quite a bit of testing, yes.

But keep in mind, it is still an outage.
