bug: integer doesn't get decoded properly if the previous value is null

[PoiScript]

SQL:

CREATE TABLE foo (
  id TEXT PRIMARY KEY,
  bar INTEGER,
  baz INTEGER
);
INSERT INTO foo (id, bar, baz) VALUES ('001', 100, 100);
INSERT INTO foo (id, bar, baz) VALUES ('002', null, 100);

Rust:

struct Foo {
    bar: Option<i32>,
    baz: Option<i32>,
}

let mut pool = PgPool::new(env!("DATABASE_URL")).await.unwrap();

let row = sqlx::query_as!(Foo, "select bar, baz from foo where id = '001'")
    .fetch_one(&mut pool)
    .await
    .unwrap();

assert_eq!(row.bar, Some(100));
assert_eq!(row.baz, Some(100));

let row = sqlx::query_as!(Foo, "select bar, baz from foo where id = '002'")
    .fetch_one(&mut pool)
    .await
    .unwrap();

assert_eq!(row.bar, None);
assert_eq!(row.baz, Some(100)); // error 

Error:

thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `Some(4)`,
 right: `Some(100)`', src/main.rs:64:5

FYI, I'm using PostgreSQL 12.1 on ArchLinux.
