whatever, i do the argument VARCHAR will be stored in double quote as
"varchar" when i check via pgAdmin GUI. Even if in command line it looks
like above.

I still have the same error message on "myrec" :
ERROR:  schema "myrec" does not exist
CONTEXT:  SQL statement "SELECT
myrec.articletypes.articletype_type"

you are using composite types right? you have to add parenthesis to
disambiguate this case:

http://www.postgresql.org/docs/8.1/interactive/rowtypes.html#AEN5789

res.article_title := myrec.(articles).title;

sorry i missed that the first time out.
