<li>Optimization: When doing an [UPDATE] on a table with [indexes on expressions],
do not update the expression indexes if they do not refer to any of the columns
of the table being updated.
<li>Added the [SQLITE_DBCONFIG_DEFENSIVE] option which disables the ability to
create corrupt database files using ordinary SQL.
<li>Added support for read-only [shadow tables] when the [SQLITE_DBCONFIG_DEFENSIVE]
option is enabled.
<li>Added the [PRAGMA legacy_alter_table] command, which if enabled causes the
[ALTER TABLE] command to behave like older version of SQLite (prior to
version 3.25.0) for compatibility.

do not update the expression indexes if they do not refer to any of the columns

<li>Allow the [xBestIndex()] method of [virtual table] implementations to return
[SQLITE_CONSTRAINT] to indicate that the proposed query plan is unusable and
should not be given further consideration.

create corrupt database files using ordinary SQL.
