     for inefficient use of space: if all but a few index keys on a page have
     been deleted, the page remains allocated.  So a usage pattern in which all
     but a few keys in each range are eventually deleted will see poor use of
!    space.  The potential for bloat is not indefinite — at worst there
!    will be one key per page — but it may still be worthwhile to schedule
!    periodic reindexing for indexes that have such usage patterns.

      most of the rows in a table and would like the table to physically shrink
      to occupy less disk space.  <command>VACUUM FULL</command> will usually
      shrink the table more than a plain <command>VACUUM</command> would.
+     The <option>FULL</option> option does not shrink indexes; a periodic
