Sqlite pool stuck when closed

[randsoy]

log::info!("size {}", self.pool.size());
log::info!("num_idle  {}", self.pool.num_idle());
self.pool.close().await;

It happens when they are different。

This is intentional, pool.close() doesn't return until all connections are released to the pool and closed.

If it's hanging, that means there is a task somewhere that is holding on to a connection and not dropping it.
