        The DROP INDEX statement removes an index added with the <a href="lang_createindex.html">
          CREATE INDEX</a> statement. The index named is completely removed from the disk.
        The only way to recover the index is to reenter the appropriate CREATE INDEX command.</p>
      <p>
        The DROP INDEX statement does not reduce the size of the database file in the default
        mode. Empty space in the database is retained for later INSERTs. To remove free
        space in the database, use the <a href="lang_vacuum.html">
          VACUUM</a> command. If
        AUTOVACUUM mode is enabled for a database then space will be freed automatically by DROP INDEX.</p>
