not be unloaded (xDlClose will not be invoked) and the extension will remain
in process memory indefinitely.  The SQLITE_OK_LOAD_PERMANENTLY return
value is useful for extensions that want to register new [VFSes].

<p>To clarify: an extension for which the initialization function returns
SQLITE_OK_LOAD_PERMANENTLY continues to exist in memory after the database
connection closes.  However, the extension is <em>not</em> automatically
registered with subsequent database connections.  This make it possible
to load extensions that implement new [VFSes].
To persistently load and register an extension that implements new SQL
functions, collating sequences, and/or virtual tables, such that those
added capabilities are available to all subsequent database connections,
then the initialization routine should also invoke [sqlite3_auto_extension()]
on a subfunction that will register those services.
