When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.

The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.

On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted.
