There's this trick:

    v_sql := 'INSERT INTO schema.parent_' || to_char(NEW.date, 'YYYYMM') ||
             '     SELECT (' || quote_literal(textin(record_out(NEW))) || '::schema.parent).*;';

    EXECUTE v_sql;

This will handle dynamic SQL and NULLs correctly, but as said already
won't match static SQL in term of performances. Just saying for people
searching simplifications.
