help: pgSQL docs and debug

From

I need to write some longer pgSQL stored procedures.

Can you help?
1. I am looking for a reference of pgSQL functions, etc.?
(I have all the books, they have just a few, I also looked all over the 
web).
If you can post a link, tia.

For example, what does the || do in pg SQL with a string?
I am looking at code examples and having a hard time to follow.


2. How do I debug pgSQL stored procedure?
Right now I write step by step.
Is there a "system.out" in pgSQL? Where does it show?
Is there a GUI editor that helps (I use pgADMIN II).

Any help appreciated.

Start from "Chapter 19. PL/pgSQL - SQL Procedural Language" on Postgresql documentation.
I think, you can find there everything you need for pl/pgsql.
After you read this, search techdocs.postgresql.org site.
Lots of examples could be find on braseiro.net (don't remember spelling)

|| has nothing to pl/pgsql. It is a part of SQL standard - string concatenation.

Use "RAISE NOTICE ''My name is: %'',some_row.name " and "RAISE EXCEPTION ..."
