This PR continues #3769 work and fixes #3596. It also seems to resolve #1847 and resolve #1168, ensuring that destroy and error events are properly issued (not using try-catch, but stream.on('error', () => {}) approach, which is the expected pattern for callbacks).


In #3769, it destroys the connection on error to ensure that the stack is not blocked, but this approach can be aggressive, as a query error shouldn't destroy the connection.

In this PR, the approach is to destroy the current stream itself on error and emits the appropriate events, ensuring its functionality and allowing users to catch errors that were not previously emitted, as reported in #1847.


Before this PR

The test that checks the events is not reached and the script is silently ended prematurely:

After this PR

Now all tests are reached:
