Nope! I've never used postgres at all. Most of my RDBMS work was done on HN NSFW ALERT - oracle :-) But your comment supports my general point, which is, that data modelling and relational schema design skills are product agnostic; normalization is normalization, as it were.

Just to point out, "PROGRESS 4GL" is a different thing, not PostgreSQL based.

It seems to be called OpenEdge Advanced Business Language these days:

And yeah, the terms you mentioned are foundational RDBMS terms, common to all reasonable implementations of RDBMS's. :)

Ok. Oracle had/has a presumeably similar thing (PL/SQL). I misread his comment to mean, postgres SQL.

Yes indeed, I meant PROGRESS 4GL, which was sort of around before all the "RDBMS" hoopla congealed all this wonderful info into a single art. Its just that your last paragraph really sounded like a quote, near-verbatim, from the very guides published by PROGRESS just for the purposes of educating people on how to make their data relatable .. but of course that is because these are natural laws for databases.
