I am getting an “invalid input syntax for type double precision” error when I return an array as part of a composite type from my C-language function. I can re-create this situation with just a type and a function.
My type is declared as follows:
CREATE TYPE my_grid AS (min_x double precision, min_y double precision, max_x double precision, max_y double precision, my_arr double precision[][]);
My function is defined as:
CREATE FUNCTION my_test()
RETURNS void AS $$
DECLARE
mine my_grid;
BEGIN
SELECT INTO mine (0.1, 0.2, 0.3, 0.4,'{{88.9}}'::double precision[][])::my_grid;
END
$$
LANGUAGE plpgsql
SECURITY DEFINER
SET search_path = public;
To get the error, I run the following query:
SELECT MY_TEST();
If I do a plain “SELECT (0.1, 0.2, 0.3, 0.4,'{{88.9}}'::double precision[][])::my_grid;” everything looks good.
Any help would be appreciated.
