This page covers the Azure-specific steps to prepare your PostgreSQL instance for ELT & CDC. After completing them, follow the common setup (sync user grants, heartbeat table, publication, and replication slot) on the PostgreSQL source for ELT & CDC page.

​
Requirements

  • Azure Single Server for PostgreSQL.
  • PostgreSQL version 10 or above.
  • Connect to the primary instance. Logical replication only works on the primary.
  • Tables with a PRIMARY KEY.

​
Enable logical replication

1

Open the Azure Database for PostgreSQL server

Go to your Azure Database for PostgreSQL server page in the Azure portal.
2

Set replication support to LOGICAL

Under Replication, set replication support to LOGICAL and click Save. Restart the server if Azure prompts you.
Azure PostgreSQL replication settings with LOGICAL support enabled

​
Next: common setup

Continue with the canonical PostgreSQL setup for the remaining steps — sync user creation, privileges (USAGE, SELECT, REFERENCES), heartbeat table, publication, and replication slot. Grant the replication attribute with ALTER ROLE integrateio WITH REPLICATION;.
