MySQLdb relies on garbage collection to close the connection. Relying
on such asynchronous event as the garbage collector is never a good idea,
and this can cause issues when the transaction associated with the
connection is started: because the connector is being replaced, it will
never be properly aborted. So do not take chances and do not leak open
connections: always close it.

So that it's more apparent that we are not leaking a potentially active
transaction on that connection.

The same error code can be used for different causes. Specifically, it can
be used for SQL-level syntax error (which this code intended to handle),
or it can be used for fulltext syntax error (which makes this code raise).
Also, drop forced-reconnection, because this means a still-established
connection make be kept around and completely detected from current
transaction, which may cause a database snapshot to be kept indefinitely
(actually, until mariadb's timeout), in turn causing performance issue
because of associated InnoDB snapshot.
