<li> The [SQLITE_READ] [authorizer callback] is invoked with a NULL column name

     for every table referenced in a query from which no columns are extracted.
<li> When using an index on an expression, try to use expression values already
     available in the index, rather than loading the original columns and recomputing
     the expression.
<li> Enhance the [flattening optimization] so that it is able to flatten views
     on the right-hand side of a LEFT JOIN.
<li> Use [replace()] instead of [char()] for escaping newline and carriage-return
