Thread: 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,
