This change can break applications that are not expecting it and

do their own string escaping according to the old rules. The

consequences could be as severe as introducing SQL-injection security
|

holes. Be sure to test applications that are exposed to untrusted

input, to ensure that they correctly handle single quotes and

backslashes in text strings.
