    number of terms on the right-hand side of the MATCH operator.
<li>Added the [fts3tokenize virtual table] to the [full-text search] logic.
<li>Query planner enhancement: Use the transitive property of constraints
    to move constraints into the outer loops of a join whenever possible,
    thereby reducing the amount of work that needs to occur in inner loops.
<li>Discontinue the use of posix_fallocate() on unix, as it does not work on all
    filesystems.





<li>Bug fix:
    Only consider AS names from the result set as candidates for resolving
    identifiers in the WHERE clause if there are no other matches. In the 
    ORDER BY clause, AS names take priority over any column names.
    Ticket [http://www.sqlite.org/src/info/2500cdb9be05 | 2500cdb9be05]
<li>Bug fix: 
    Prevent excessive stack usage in the [full-text search] engine when processing
