postgres 8.2.4 new installation - trying to get autovacuum to work

Hi, I'm new to 8.2 and trying to get our testing server to autovacuum.

I have a table that has roughly 116000 rows

I have applied 40,000 updates.

The applicable postgresql.conf parameters are as follows:

autovacuum | on

autovacuum_analyze_scale_factor | 0.1

autovacuum_analyze_threshold | 250

autovacuum_freeze_max_age | 200000000

autovacuum_naptime | 60

autovacuum_vacuum_cost_delay | -1

autovacuum_vacuum_cost_limit | -1

autovacuum_vacuum_scale_factor | 0.2

autovacuum_vacuum_threshold | 500

stats_row_level | on

stats_start_collector | on

given the scale factor and the threshold I expected autovacuum to kick in at
about the 23000 th update

I am looking at the pg_logs Should I be looking elsewhere?
Log_min_duration_statement currently set to 2000 milliseconds.

The updates show in the logs. The vacuum does not.

Any help would be appreciated. Thank you,
