Hi
i'm plannig to use Slony to do some replication between 2 Ubuntu-Systems
running postgresql 9.1 and 9.3.
reading this page http://slony.info/ i'm a little bit confused which
slony-version would be the best to start with.
2.2.2 , 2.1.4 or 2.0.8?
It's a production system but not for commercial (critical) use. Just an
OpenStreetmap database of ~600GB
regards
walter

If it's "not production," (and I understand all the nuances of "sort of production") why not just 9.3 both of them and use built-in replication? What are you trying to accomplish that you feel Slony will do better?

Ok, it's not for commercial use (no company loosing money if it fails), but
i have to do this tasks and would like to have the database online as long
as possible.
- move the database to another system
- reinstall the old system starting from scatch (ubuntu and all apps
including postgresql/postgis)
- upgrade from 9.1 to 9.3
my plan: install 9.3 on new system, move database using slony, reinstall new
system with 9.3, move database back, keep slony alive for fallback. i will
not upgrade the running server to 9.3 without fallback.
ok, you say "do it without slony"
than i have to install 9.1 on the new server, sync databases, rebuild old
server with 9.1, resync back, upgrade new server to 9.3, upgrade
backup-Server to 9.3
so i ask again: which version of slony should i use - if i do it with slony?
Regards
walter

I would use 2.2.
BTW, we do have a separate mailing list for slony:
http://lists.slony.info/mailman/listinfo/slony1-general

Thanks. ok 2.2 should be fine.
i know about that mailing-list (even have an account there) but i can't use
it . I prefer nabble as interface and could not find slony on nabble.
if i have technical questions about slony, i'll try to go the direct way.
