+ <productname>PostgreSQL</productname> is unable to reuse index pages
+ in some cases. The problem is that if indexed rows are deleted, those
+ indexes pages can only be reused by rows with similar values. In
+ cases where low indexed rows are deleted and newly inserted rows have
+ high values, disk space used by the index will grow indefinately, even
+ if <command>VACUUM</> is run frequently.
