Forum OpenACS Q&A: Contribute to the PL/pgSQL CookBook
Come to http://www.brasileiro.net/postgres and contribute your own PL/pgSQL (or PL/Tcl, PL/Perl) function or trigger! This will help many Postgres users, both novice and experienced, to use its procedural languages.
The CookBook has several sections, and you can add your own. No login is required, just come and contribute.
Once again http://www.brasileiro.net/postgres
Oh, did I mention that you get your own "PostgreSQL Powered" button when you contribute a function/trigger? :)
I just finished the revamping of the PL/pgSQL documentation. IMHO it's much much better than the current docs. It has a coherent structure, more subsections, many more examples, more explanations, etc.
I submitted to the PG team and it should be incorporated in PG 7.1. You can look at them now at http://www.brasileiro.net/postgres
Don, I agree entirely. When I started looking at the PG website a few weeks ago, I was somewhat shocked/amused that it's a static site with no dynamic database backed features at all.
