Older snapshots require migration, so it's recommended to use the latest version
Documentation for restoring from these files is available at state-snapshot.md.
Upgrade instructions
It is possible to upgrade to this release from previous versions.
A ledger state replay may be necessary from genesis. The existing db is not affected by this, only the ledger snapshot.
If you restart db-sync with different config or genesis files, you need to initially delete the ledger state snapshots files.

Postgres setup
It is advised to use a postgres version >= 14. The default docker postgres has been upgraded to 14.10-alpine.
There is a postgres requirement for users that don't use docker-compose and have to manually configure postgres:
It is advised to increase `maintenance_work_mem` from the Postgres configuration to 0.5GB - 1GB (the default is 64MB).
Also use the default (2) or higher for `max_parallel_maintenance_workers` (this parameter was introduced in `postgres` version 11)
Notes
When running db-sync make sure you enable only the data that you need. This can be configured in the db-sync config file as documented here configuration.md

Known issues
- Using "only-utxo" preset has a bug: it enables the metadata instead of the multiassets. When using this flag, 13.4.0.1 tag should be used https://github.com/IntersectMBO/cardano-db-sync/releases/tag/13.4.0.1
- "pool_stats" preset will be renamed to "pool_stat" in next releases.
