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.

^If there are multiple ATTACH-ed database files that are being +** modified as part of a transaction commit, then the autovacuum pages +** callback is invoked separately for each file. +** +**
The callback is not reentrant. The callback function should +** not attempt to invoke any other SQLite interface. If it does, bad +** things may happen, including segmentation faults and corrupt database +** files. The callback function should be a simple function that +** does some arithmetic on its input parameters and returns a result. +** +** ^The X parameter to sqlite3_autovacuum_pages(D,C,P,X) is an optional +** destructor for the P parameter. ^If X is not NULL, then X(P) is +** invoked whenever the database connection closes or when the callback +** is overwritten by another invocation of sqlite3_autovacuum_pages(). +** +**
^There is only one autovacuum pages callback per database connection. +** ^Each call to the sqlite3_autovacuum_pages() interface overrides all +** previous invocations for that database connection. ^If the callback +** argument (C) to sqlite3_autovacuum_pages(D,C,P,X) is a NULL pointer, +** then the autovacuum steps callback is cancelled. The return value +** from sqlite3_autovacuum_pages() is normally SQLITE_OK, but might +** be some other error code if something goes wrong. The current +** implementation will only return SQLITE_OK or SQLITE_MISUSE, but other +** return codes might be added in future releases. +** +**
If no autovacuum pages callback is specified (the usual case) or +** a NULL pointer is provided for the callback, +** then the default behavior is to vacuum all free pages. So, in other +** words, the default behavior is the same as if the callback function +** were something like this: +** +**
+** unsigned int demonstration_autovac_pages_callback(
+** void *pClientData,
+** const char *zSchema,
+** unsigned int nDbPage,
+** unsigned int nFreePage,
+** unsigned int nBytePerPage
+** ){
+** return nFreePage;
