ConnectionError - Session terminated by database without notifying the library

[linhub15]

Using a cloud managed DB often terminates sessions without notifying the library. This causes ConnectionError because the library was not notified of the cancelled connection.

There is a TODO comment mentioned that this will be fixed.

... will be removed once we move to async handling of messages by the frontend ...
https://github.com/denodrivers/postgres/blob/main/connection/connection.ts#L167-L171

Is there a workaround in the meantime?

Would it be wrong to recursively call Connection.query(...)?
