sql: name type does not have same size limit as postgres

Repro:
```
CREATE TABLE NAME_TBL(f1 name);
INSERT INTO NAME_TBL(f1) VALUES ('1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQR');
INSERT INTO NAME_TBL(f1) VALUES ('1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqr');
INSERT INTO NAME_TBL(f1) VALUES ('asdfghjkl;');
INSERT INTO NAME_TBL(f1) VALUES ('343f%2a');
INSERT INTO NAME_TBL(f1) VALUES ('d34aaasdf');
INSERT INTO NAME_TBL(f1) VALUES ('');
INSERT INTO NAME_TBL(f1) VALUES ('1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ');
SELECT * FROM NAME_TBL;
```

Postgres limits the `name` type to 63 chars:
```
f1
-----------------------------------------------------------------
1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQ
1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopq
asdfghjkl;
343f%2a
d34aaasdf

1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQ
```

CRDB does not appear to impose a limit:
```
f1
----------------------------------------------------------------------------
1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQR
1234567890abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqr
asdfghjkl;
343f%2a
d34aaasdf

1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
```
