RAISE with C?

[Elliot Chance <elliotchance@xxxxxxxxx>]

Hi,

Is it possible to do the equivalent of RAISE EXCEPTION inside a C-function? Like this:


PG_FUNCTION_INFO_V1(check_something);
Datum check_something(PG_FUNCTION_ARGS)
{
	// RAISE EXCEPTION 'bla bla'
}

CREATE OR REPLACE FUNCTION do_check() RETURNS text AS $$
BEGIN
	PERFORM check_something();
	RETURN 'All good';
EXCEPTION
	WHEN RAISE EXCEPTION THEN
		RETURN 'Something bad';
END;
$$ LANGUAGE plpgsql IMMUTABLE;


That code may not work but you get the idea, I want to throw an exception from a C function that can be caught in PL/pgSQL. Also is it further possible to catch the message that RAISE EXCEPTION sends? Like 'Something bad: bla bla'

Thanks,
Elliot
