CLUSTER removing index from table?

Has anyone else seen this sort of behaviour?  After my CLUSTER command
my other index has vanished!  I know someone mentioned they had done a
lot of work on CLUSTER, so perhaps this has been fixed.

I'm running Debian 7.0.2-4, on i386.

Regards,                Andrew.
