postgres 9.0 streaming replication for reporting

[LD50]

Hello,

I'm designing a plan to upgrade from postgres 8.4. Our current setup includes three servers/dbs:

1. Production
2. Warm Standby (WAL shipping)
3. Reporting (built by ETL jobs)

I was hoping to have a similar setup with 9.0, but have the Reporting db maintained by replication instead of the ETL jobs. All the articles I read about Streaming replication tend to use the replicated box as a Hot Standby only... Is my setup possible? Know of any articles that will help me? Any suggestions of other ways I should design the reporting (ie. Greenplum)?

Here is the new setup I had in mind:

1. Production
2. Hot Standby
3. Reporting by Streaming Replication

Thanks!
