Hello
you have to use parenthesis, because parser don't distinguish between
variants schema.table.column and variable.field.attrib
example:
postgres=# create or replace function trgbody() returns trigger as $$
begin
raise notice '%', (new.a).a;
return new;
end $$ language plpgsql;
CREATE FUNCTION
postgres=# create type xx as (a integer, b integer);
CREATE TYPE
postgres=# create table g(a xx);
CREATE TABLE
postgres=# create trigger ggg before insert on g for each row execute
procedure trgbody();
CREATE TRIGGER
postgres=# insert into g values('(10,20)');
NOTICE: 10
INSERT 0 1
