/* In 'lsm_open()' we don't update the page and block sizes in the
** Filesystem for 'readonly' connection. Because member 'db->pShmhdr' is a
** nullpointer, this prevents loading a checkpoint. Now that the system is
** live this member should be set. So we can update both values in
** the Filesystem.
**
** Configure the file-system connection with the page-size and block-size
** of this database. Even if the database file is zero bytes in size
** on disk, these values have been set in shared-memory by now, and so
** are guaranteed not to change during the lifetime of this connection. */
