Automatically switch to primary database with 'withReplicas'

[LaurinBrechter]

I use the read replicas feature with the following configuration.

export const masterDb = drizzle({
  connection: process.env.DATABASE_URL!,
  schema: { ...schema, ...authSchema },
  logger: new MyLogger("master"),
});

export const replicaDb = drizzle({
  connection: process.env.DATABASE_URL_REPLICA!,
  schema: { ...schema, ...authSchema },
  logger: new MyLogger("replica"),
});

export const db = withReplicas(masterDb, [replicaDb]);

If my replica database isn't available for read operations, I just get an error and my app will stop working. Wouldn't it make more sense if drizzle detects the error and then automatically switches to the primary db (or maybe switches after some retries)? Or is this something my code needs to handle in something like a try catch?
