EnterpriseDB seems to be the corporate benefactor behind PostgreSQL, and is run by what looks to be a lot of former Redhat guys. There's definitely commercial support out there.

As a programmer, I would love to use PostgreSQL everywhere over all the options you mention... Mongo has a pretty decent replication/failover setup, better than MS-SQL imho, and MS-SQL being a close second... administering PostgreSQL for high availability seems like an exercise in frustration, with lots of after-thought bolted on solutions.

I think by the time we see either 9.6 or so, or 10.0 (depending on how versioning goes), with PL/v8 and sane replication/failover solution in the box, it'll become my db of choice.

Most of what I use MongoDB for today can be done almost as nicely in PostgreSQL, and the latter can do a lot the former would trip on.
