One amazing little extension of Postgres I found lately is Multicorn http://multicorn.org/ http://multicorn.org/ It lets you write a Foreign Data Wrapper in Python. One Python class with two methods is enough to e.g. expose files in a proprietary data format as normal Postgres tables. That's what I did in about two hours, the users can now query their data with SQL and access it in a programming language of their choice, as long as the language has a Postgres driver (most have). Really cool.
