Manual Replication Setup
Set up replication with Airbyte, Estuary, Fivetran, and other tools.
This guide covers setting up manual replication using external tools. If you prefer a simpler, managed solution, see Replication instead.
This guide is for replicating data to external systems using your own tools. For deploying read-only databases across multiple regions, see Read Replicas instead.
Prerequisites
To set up replication, the following is recommended:
- Instance size of XL or greater
- IPv4 add-on enabled
To create a replication slot, you will need to use the postgres user and follow the instructions in the external replication setup guide.
If you are running Postgres 17 or higher, you can create a new user and grant them replication permissions with the postgres user. For versions below 17, you will need to use the postgres user.
If you are replicating to an external system and using any of the tools below, check their documentation first. Additional information is provided where the setup with Supabase can vary.
Estuary has the following documentation for setting up Postgres as a source.
