SQL tab of view contains following:

CREATE OR REPLACE VIEW public.testviewcomments
AS
SELECT testtablecomments.field
FROM testtablecomments;
ALTER TABLE public.testviewcomments
OWNER TO postgres;
COMMENT ON VIEW public.testviewcomments
IS 'View comment';
COMMENT ON COLUMN public.testviewcomments.field
IS Field comment;

But the last statement should be:
COMMENT ON COLUMN public.testviewcomments.field
IS 'Field comment';
