Hi Tom, sorry for asking again on the same issue but i try to figure out how i have to deal with and how strong i can trust the postgres-docs and -books. in every documentation(7.5 too) i can read that i can pass a row to a plpgsql function. but how u know it does not work. i am still thinking i am wrong or are really all that docs wrong? And if the documentation is wrong, is this normal for the postgres-docs? I dont wanna steal your time, but i can not understand it. regards thomas ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
