Hi Mark,
For me, Pentaho has delivered quite good results in the past, and being an open source offering it would probably work OK with postgresql. Jasper reports also seems to have made it into BI space, and I would assume it'd work with postgresql too or so I recall. Both are open source projects/products with strong industry adoption, so if you're going to advice against MS tools, they'd be more likely to be considered as alternatives.
