     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
     characters embedded in strings in the .dump output from the [command-line shell].
