If you CLUSTER there is no reason to REINDEX; indexes are rebuilt by
the CLUSTER command.
 
Also, if you do a good job with regular VACUUMs, there isn't any bloat
to fix.  In that case a regular CLUSTER would only be needed if it was
worth the cost to keep data physically organized in the index
sequence.
