  Information about views is stored in the SQLITE_MASTER table.  If an older
  version of SQLite attempts to read a database that contains VIEW information
  in the SQLITE_MASTER table, the parser will not understand the new syntax
  and you will get an error.  Also, the
  way SQLite keeps track of unused disk blocks in the database file
  changed slightly.
  If an older version of SQLite attempts to write a database that
  was previously written by version 2.4.0 or later, then it may leak disk
  blocks.</td>

<p>
To perform a database reload, have ready versions of the
<b>sqlite</b> command-line utility for both the old and new
version of SQLite.  Call these two executables "<b>sqlite-old</b>"
