inserting into w/ column names doesn't work properly

Describe the bug

There are two problems right now on 0.1.14-rc:

1. The RisingWave doesn't insert a null by default for ignored columns
2. The data inserted is not aligned w/ the column names

To Reproduce

On RisingWave 0.1.14-rc

dev=> create table t (v1 int, v2 int, v3 int);
CREATE_TABLE
dev=> insert into t (v1, v2, v3) values (1, 2, 3);
INSERT 0 1
dev=> insert into t (v2, v3) values (2, 3);
ERROR:  QueryError: Bind error: INSERT has more target columns than expressions
dev=> insert into t (v2, v3, v1) values (2, 3, 1);
INSERT 0 1
dev=> select * from t;
 v1 | v2 | v3
----+----+----
  1 |  2 |  3
  3 |  1 |  2
(2 rows)

Expected behavior
