# Outros parâmetros que afetam o autovacuum
<a name="Appendix.PostgreSQL.CommonDBATasks.Autovacuum.OtherParms"></a>

A consulta a seguir mostra os valores de alguns dos parâmetros que afetam diretamente o autovacuum e seu comportamento. Os [parâmetros de autovacuum](https://www.postgresql.org/docs/current/static/runtime-config-autovacuum.html) são descritos inteiramente na documentação do PostgreSQL.

```
SELECT name, setting, unit, short_desc
FROM pg_settings
WHERE name IN (
'autovacuum_max_workers',
'autovacuum_analyze_scale_factor',
'autovacuum_naptime',
'autovacuum_analyze_threshold',
'autovacuum_analyze_scale_factor',
'autovacuum_vacuum_threshold',
'autovacuum_vacuum_scale_factor',
'autovacuum_vacuum_threshold',
'autovacuum_vacuum_cost_delay',
'autovacuum_vacuum_cost_limit',
'vacuum_cost_limit',
'autovacuum_freeze_max_age',
'maintenance_work_mem',
'vacuum_freeze_min_age');
```

Enquanto todos estes afetem o autovacuum, alguns dos mais importantes são:
+ [maintenance\$1work\$1mem](https://www.postgresql.org/docs/current/static/runtime-config-resource.html#GUC-MAINTENANCE_WORK_MEM)
+ [autovacuum\$1freeze\$1max\$1age](https://www.postgresql.org/docs/current/static/runtime-config-autovacuum.html#GUC-AUTOVACUUM-FREEZE-MAX-AGE)
+ [autovacuum\$1max\$1workers](https://www.postgresql.org/docs/current/static/runtime-config-autovacuum.html#GUC-AUTOVACUUM-MAX-WORKERS)
+ [autovacuum\$1vacuum\$1cost\$1delay](https://www.postgresql.org/docs/current/static/runtime-config-autovacuum.html#GUC-AUTOVACUUM-VACUUM-COST-DELAY)
+ [ autovacuum\$1vacuum\$1cost\$1limit](https://www.postgresql.org/docs/current/static/runtime-config-autovacuum.html#GUC-AUTOVACUUM-VACUUM-COST-LIMIT)
