BUG: If a query fails, it never ends

I have this code:

try {
    await pg.unsafe("My query");
} catch (e) {
    // whatever
}

The connection is inmediately lost as a test that I have is to close the server socket just when the query starts, so I'm receiving an Error: read ECONNRESET in the catch.

But when I try to end the connection, it lasts forever:

await pg.end();

I went into the code and what I found is that a connection has a rejected query associated, so it just waits for it to finish, but it is already finished, so it waits forever:

Obviously I don't want to add a timeout to the end callback as a workaround. All resources should be cleaned properly.

Trace the pg.unsafe failure path into pg.end and connection cleanup, using the ECONNRESET reproduction described in the issue. Done means a failed query does not leave shutdown waiting forever and pg.end completes without a timeout workaround.
