No, the big problem is that you don't consider your fellow DBA's
reliable. That's a problem you need to solve rather sooner than later.
Another problem is that you are apparently logging all SQL statements.
Not only does that store the SQL for changing database users, it will
also slow down your database. You should really only log all
statements if you're debugging something, and only temporarily.
Of course it would be nice if those passwords would be encrypted, but
they are simply part of SQL statements - there is no means in SQL to
distinguish a password string literal from any other type of literal,
until the statement hits the database.
