Keep reading... from the same paragraph:
Clustering is a one-time operation: when the table is subsequently
updated, the changes are not clustered. That is, no attempt is made to
store new or updated rows according to their index order. If one wishes,
one can periodically recluster by issuing the command again.
There is absolutely no way to enforce any kind of table ordering in
PostgreSQL as soon as you do *anything* that changes the table.
And like others said, I think you need to re-think how you're doing
this... :)
