## Postgres parameters are automatically tuned now
The playbook has provided some hints about [Tuning PostgreSQL](docs/maintenance-postgres.md#tuning-postgresql) for quite a while now.
From now on, the [Postgres Ansible role](https://github.com/devture/com.devture.ansible.role.postgres) automatically tunes your Postgres configuration with the same [calculation logic](https://github.com/le0pard/pgtune/blob/master/src/features/configuration/configurationSlice.js) that powers https://pgtune.leopard.in.ua/.
Our [Tuning PostgreSQL](docs/maintenance-postgres.md#tuning-postgresql) documentation page has details about how you can turn auto-tuning off or adjust the automatically-determined Postgres configuration parameters manually.
People who [enable load-balancing with Synapse workers](docs/configuring-playbook-synapse.md#load-balancing-with-workers) no longer need to increase the maximum number of Postgres connections manually (previously done via `devture_postgres_process_extra_arguments`). There's a new variable (`devture_postgres_max_connections`) for controlling this number and the playbook automatically raises its value from `200` to `500` for setups which enable workers.
