Bug reference:      4487
Logged by:          anonymous
Email address:      [EMAIL PROTECTED]
PostgreSQL version: 8.3
Operating system:   BSD
Description:        CLUSTER does not take account of VACUUM statistics
Details: 

CLUSTER still does a full page scan although there are 0 dead rows on table.


Reproduction:
1. CREATE table
2. INSERT records (e.g. bulk load)
3. VACUUM ANALYZE table
4. CLUSTER table

Expected behavior:
in step 4 clustering starts from first dead page only.
