Mladen,
You would need to check the mailing lists. The release notes
have it as being a clock sweep algorithm starting in version
8. Then additional changes were added to eliminate the cache
blowout caused by a sequential scan and by vacuum/autovacuum.
I do not believe that there are any parameters available other
than total size of the pool and whether sequential scans are
synchronized.
Regards,
Ken
