pool.end() not working

[ashercsulb]

I ran the sample code you provided and the pool.end() does not seem to work.
Code at: https://node-postgres.com/features/pooling

Code
console.log("start async query");
const result = await pool.query("SELECT NOW()");
console.log("async query finished, now is: ", result.rows[0].now);

console.log("starting callback query");
pool.query('SELECT NOW()', (err, res) => {
console.log("callback query finished, res is: ", res.rows[0].now);
});

console.log("calling end");
await pool.end();
console.log("pool has drained");

Output
Note: Missing the "callback query finished..." text.
start async query
async query finished, now is: 2023-12-21T01:54:14.233Z
starting callback query
calling end
pool has drained

Should be as follows:
start async query
async query finished, now is: 2023-12-21T01:54:14.233Z
starting callback query
calling end
callback query finished.... -- Missing
pool has drained

When I comment out the following:
await pool.end();
I get the expected behavior ("callback query finished..." is printed at the end).

Output
start async query
async query finished, now is: 2023-12-21T01:55:50.634Z
starting callback query
calling end
pool has drained
callback query finished, res is: 2023-12-21T01:55:50.666Z
