Hello I actualised plpgsql tutorial on address http://www.pgsql.cz/index.php/PL/pgSQL_%28en%29#Design_of_triggers_in_PL.2FpgSQL
I hope so this document can be useful for people who start with plpgsql. Sorry - my English is good for reading mailing list and coding in C lang. Can some native english speaker look on this document and correct some errors and mistakes?
