Postgres Archeology
In a previous post I have ported a Turing Machine (TM) in SQL down to Postgres 7.3.
I report here my fruitless attempts at running previous versions of Postgres on a Debian or Ubuntu Linux. They would not configure and/or compile, at least with the minimal effort I was ready to undergo: writing portable-to-the-future system-dependent C code does not work. Basically, the code from 15 years ago is lost unless you run it on a system from 15 years ago, which may require a hardware from 15 years ago as well, or maybe a VM.
