Microsoft-Funded Linux Studies Benefit ... Microsoft

Re:True if they assume Oracle and WebLogic everywh

You've obviously never used Postgres. Postgres is in the same league as MS SQL Server, Oracle, DB2, and others. It is not quite as tunable as Oracle, and Oracle can scale higher, but not higher enough to be in a completely different league.

Comparing PG w/ Access shows that you've never used PG. PG supports views, triggers, constraints, the ability to write functions in many languages, indexes, partial indexes, some table inheritance support, includes a genetic query optimizer, can do views of "group by" clauses (and optimizes them very well), can do updateable views, has a really nice "rules" system for rewriting queries, has write-ahead logging, support for multiple transaction isolation levels, and several other features I can't think of here.

The limitations of Postgres are: no support for configurable tablespaces, no automated point-in-time recovery (however, Oracle's PITR is quite limited, too), doesn't work with protocols requiring two-phase commits (PG uses MVCC, which uses less locking), cannot do nested transactions, and does not have a built-in automated replication solution (although third-party products and open-source projects are available).

These limitations are only problematic in the largest of deployments, however, and most of them can be worked around. The only one which would be problematic for most database apps is the lack of support for nested transactions.

"As for JBoss vs. Weblogic, i don't have enough experience with either to make a valid comparison, but Weblogic is ceratinly a much more capable product by features alone."

Actually, JBOSS has led the way in features, with Weblogic playing catch-up. I'm sure there's some things that Weblogic has that JBOSS doesn't, but most people I know who have used both prefer JBOSS.
