This example shows the usage of Postgres 17 failover replication slots with Postgres' SQL-based interface to logical replication, as well as with Decodable. It accompanies this blog post.
To run this example, you’ll need Docker. For running the Decodable-specific part, you'll also need to have the following:
- A free Decodable account
- The Decodable CLI installed on your machine
- A free ngrok account
Retrieve your auth token from the ngrok web UI and put it into a file .env like so:
NGROK_AUTHTOKEN=<your token>
Start everything by running:
docker compose up
Then, follow the instructions from the blog post.
