To quote the fine documentations at:
 
www.postgresql.org/docs/8.1/interactive/sql-cluster.html
 
| When a table is clustered, PostgreSQL remembers on which index it
| was clustered. The form CLUSTER tablename reclusters the table on
| the same index that it was clustered before.
| 
| CLUSTER without any parameter reclusters all the tables in the
| current database that the calling user owns, or all tables if
| called by a superuser. (Never-clustered tables are not included.)
