SELECT test('hello','world');
If you aren't getting the result you expect, then you have made a
mistake in your function name, parameters, return type, or a syntax
error in the function itself.
For example, if you do in fact have the function:
CREATE FUNCTION test (VARCHAR, VARCHAR) RETURNS VARCHAR AS '
DECLARE ....
And if
SELECT test('hello','world');
returns
Parser Error at or near ';'
then the database is telling you that you have a bad function, not that
it doesn't understand the SELECT.
