<li><p> If the change to table X also affects other tables or indexes or
triggers are views within schema, then run [UPDATE] statements to modify
those other tables indexes and views too.  For example, if the name of
a column changes, all FOREIGN KEY constraints, triggers, indexes, and
views that refer to that column must be modified.
<p><em>Caution:</em>  Once again, making changes to the sqlite_master 
table like this will render the database corrupt and unreadable if the 
change contains an error.  Carefully test of this entire procedure
on a separate test database prior to using it on
a database containing important data and/or make backup copies of
important databases prior to running this procedure.

<li><p> Increment the schema version number using
[PRAGMA schema_version | PRAGMA schema_version=X] where X is one
more than the old schema version number found in step 2 above.
