Description:
It would be cool to have an option to the DELETE statement, that securely deletes the
records from memory and hard disk, just like these various "wiping"-tools do for files.
This can be done by overwriting it with ones, zeros and random data several times.

How to repeat:
?!

Suggested fix:
Some option like:

DELETE SECURELY FROM mytable WHERE id = 7

I'd be happy about this, too.

A related thing would be to have a secure update of an existing record, ensuring that
overwritten data is really gone:

UPDATE SECURELY customers SET password="encryptedpasswordstring" WHERE id=1234;
