What I don't know is how to securely erase information from a
database.
If the material is that sensitive, and you only want to selectively
delete the information, the only way is to:
1) delete the information from the database using the commercial means,
2) export the database
3) Inspect the exported data to ensure all the sensitive information
is deleted
4) import the database to another storage system.
5) destroy (degauss, wipe) the original storage system.
6) the truly paranoid would destroy the raid controllers also (since
it contains NVRAM)
Not trivial...
