| When using the LangGraph API, you don't need to implement or configure checkpointers manually. The API handles all persistence infrastructure for you behind the scenes. | ||

Unrelated but noticed while I was doing this so I decided to fix as well!

| If you are using Postgres or Redis to store short and/or long-term memory, you will need to call the LangGraph-provided `saver` or `store`'s `setup` method before you can use it with your database. |

This applies to any checkpointer or store really - any DB-backed persistence implementation would have migrations.
The convention is to define a setup() method to run the required migrations for that instance, but the user should check with their specific implementation of the BaseCheckpointSaver or BaseStore to confirm.
We'd recommend running migration as a dedicated deployment step. Or you can ensure they're run as a part of server startup.
