deployments where no applciation services are in use can be upgraded as normal.

<summary><b>Recovering from an incorrect upgrade</b></summary>
If the database schema is upgraded *without* stopping the worker responsible
for AS traffic, then the following error may be given when attempting to start
a Synapse worker or master process:
```
**********************************************************************************
Error during initialisation:
Postgres sequence 'application_services_txn_id_seq' is inconsistent with associated
table 'application_services_txns'. This can happen if Synapse has been downgraded and
then upgraded again, or due to a bad migration.
To fix this error, shut down Synapse (including any and all workers)
and run the following SQL:
SELECT setval('application_services_txn_id_seq', (
SELECT GREATEST(MAX(txn_id), 0) FROM application_services_txns
));
See docs/postgres.md for more information.
There may be more information in the logs.
**********************************************************************************
```
This error may also be seen if Synapse is *downgraded* to an earlier version,
and then upgraded again to v1.57.0 or later.
In either case:
1. Ensure that the worker responsible for AS traffic is stopped.
2. Run the SQL command given in the error message via `psql`.
Synapse should then start correctly.
