How do I debug this when the PID times out?

I ran a request that stores data into AWS. Is there a way to check the PID shared in the error logs?

app_1         | [error] Postgrex.Protocol (#PID<0.574.0>) disconnected: ** (DBConnection.ConnectionError) client #PID<0.3593.0> timed out because it queued and checked out the connection for longer than 15000ms
app_1         |
app_1         | #PID<0.3593.0> was at location:
app_1         |
