Hi all,
CREATE TYPE my_type AS (a int,b int,c int,d int,e int
);
CREATE FUNCTION text_to_my_type(text)
RETURNS my_type
AS 'my_lib.so'
LANGUAGE 'C' IMMUTABLE STRICT;
CREATE CAST (text AS my_type) WITH FUNCTION text_to_my_type (text);
SELECT ('1:2:3:4:5'::text::my_type).*;
This results in the text_to_my_type(text) function being called no less
than 5 times. Once for each element.
Is this the desired behaviour, or a bug?
