If one were to have built something on postgresql 5 years ago, they would have
had to do it on 7.3. Whenever anyone posts a problem on 7.3, the first thing
people do now days is jump up and down waving thier arms about while
exclaiming how quickly they should upgrade. While I am certain there are even
older versions of postgres still running in production out there, I'd have to
say that the core developers for this project do not release software with
the expectation that you will use if for more than 5 years.
