Hi, so I have a master-slave set of database servers that are running
postgres 9.0 using streaming replication and I'd like to migrate them
to 9.1.  My question is, can 9.0 do streaming replication to 9.1?  If
not, what's the best way to upgrade a production database to 9.1 with
no downtime?

I also have a number of 8.4 servers that I'd like to upgrade to 9.1,
can 8.4 ship WAL files to 9.1?

Thanks,
Scott
