Following discussion on -hackers, the attached patch implements
- remove stats_row_level and stats_block_level stats, replaced with
single stats_collection = on | off parameter, default on
- remove stats_collector_start and make it always start
Includes doc and test changes.
Performance test results please; if they're neutral we should be good to
apply this.
