Just tried. Should ORCA reuse same transno here?
```
CREATE FUNCTION my_sum_trans(state int, val int) RETURNS int AS $$
BEGIN
RETURN state + val;
END;
$$ LANGUAGE plpgsql;
CREATE AGGREGATE my_sum1(int) (
SFUNC = my_sum_trans,
STYPE = int,
INITCOND = '0'
);
CREATE AGGREGATE my_sum2(int) (
SFUNC = my_sum_trans,
STYPE = int,
INITCOND = '0'
);
postgres=# set debug_print_aggref_in_explain to on;
SET
postgres=# explain select my_sum1(v1), my_sum2(v2) from tgb1;
