Connection does not close in 0.5.13

[phungleson]

I am running tests and at beginning of test I have line like this.

let pool = PgPoolOptions::new()
        .max_connections(5)
        .connect(&url)
        .await
        .unwrap()
// clean up old database

And at the end of each test I have a line like this

pool.close().await;

First test runs well, but second tests onwards throw error that there is still connection when it tries to clean up old database

Everything runs well with 0.5.10.

This might be related to the issue: #1776.

I can confirm. We have a lot of tests, all of which runs a function to create a connection pool. After running cargo update which bumped sqlx (and sqlx-core) to 0.5.13, the number of DB connections started growing while churning through the tests, leading to test failures when we hit the connection limit.

Pinning the sqlx-core version to 0.5.11 fixes that.
