Set up manual replication
Set up replication with Airbyte, Estuary, Fivetran, and other tools.
This guide covers setting up manual logical replication using your own tools. If you prefer a managed solution through Supabase ETL, read the external replication (ETL) setup guide instead.
This guide is for replicating data to destination 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 logical replication example.
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 a destination 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.
