Scheduled checks for Odoo autovacuum thresholds and scale factors

Database Autovacuum Tuning

Database Autovacuum Tuning helps administrators keep PostgreSQL healthy by exposing recommended autovacuum settings in Odoo. It provides guidance and documentation for sizing thresholds and scale factors so large, busy databases avoid table bloat and excessive vacuum lag. Use it to standardize autovacuum configuration across environments and speed up maintenance operations without manual tuning.

This module is mostly useful for PostgreSQL <= 17. PostgreSQL 18.0 introduces the autovacuum_vacuum_max_threshold parameter, which already provides the capability this module targets.

The pgstattuple extension must be installed on the database.

Important

This is an alpha version, the data model and design can change at any time without warning. Only for development or testing purpose, do not use in production. More details on development status

Usage

1. Install the module on the database you want to tune.

2. Go to Settings > Technical > Database Structure > Database Autovacuum Tuning and review the recommended thresholds and scale factors.

3. If needed, override the defaults using the following system parameters:

   • database_autovacuum_tuning.autovacuum_vacuum_max_threshold

   • database_autovacuum_tuning.autovacuum_vacuum_analyze_max_threshold

4. The configuration parameters are applied to tables by the daily cron job. When the number of dead tuples in a table exceeds the vacuum threshold, it applies the following configuration:

   ALTER TABLE {schemaname}.{tablename} SET (
        autovacuum_vacuum_scale_factor = 0,
        autovacuum_vacuum_threshold = %s,
        autovacuum_analyze_scale_factor = 0,
        autovacuum_analyze_threshold = %s
   )

5. Monitor vacuum activity and table bloat, then adjust the settings if your workload changes.
