Good to know that such tool is available now. Hopefully it'll be
integrated to the core distribution of postgres. 
Is the tool capable of migrating earlier version such as 7.4.5 and 8.0
to the latest ?
 
Thanks,

In order to do the same you can use pg_migrator
(http://pgfoundry.org/projects/pg-migrator/) as well. It will take a LOT
less time then normal backup/restore.

	Hello,
	I need to get data migrated from a pg8.1 cluster to a pg8.2
cluster and was wondering how well slony will accomplish this task.
	The database size is about 250GB, so doing a dump and restore
will take longer than the maintenance window for system downtime. 
	I have read several posts on the postgres mailing lists that
people recommend using slony to do major version upgrades, so I thought
to give it a try.
	One of the concerns I have is regarding the limitation that
slony does not support large objects, is this referring to the postgres
LargeObject type? 
	ie are bytea fields of significant size replicated?

	Also, is there a guide to configuring Slony-I on an active
system, or is the procedure the same (aside for the standard "backup all
data before you begin")  

	thanks
