<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].
<li> Avoid unnecessary foreign key processing in UPDATE statements that do not
     touch the columns that are constrained by the foreign keys.
<li> On a DISTINCT query that uses an index, try to skip ahead to the next distinct
     entry using the index rather that stepping through rows, when an appropriate
     index is available.
<li> Avoid unnecessary invalidation of [sqlite3_blob] handles when making
     changes to unrelated tables.
<li> Transfer any terms of the HAVING clause that use only columns mentioned in
     the GROUP BY clause over to the WHERE clause for faster processing.
<li> Reuse the same materialization of a VIEW if that VIEW appears more than
     once in the same query.
