Hi, I like the clarification but I think that:
A higher <literal>leaf_fragmentation</literal> indicates that the physical order of the index leaf
pages increasingly deviates from their logical order. Would be cleaner than:The higher <literal>leaf_fragmentation</literal> is, the less the physical order of the index leaf pages corresponds to the logical order we would have just after
a <command>REINDEX</command>. -- Benoit Lobréau Consultant http://dalibo.com
