Checking Whether session_replication_role of the Destination Database Is correctly Set

PostgreSQL Synchronization

Table 1 Checking whether the session_replication_role value of the destination database is correctly set

Check Item

Whether the session_replication_role value of the destination database is correctly set.

Description

The session_replication_role parameter of the destination database is not set to replica. Data synchronization may fail when the synchronized table has associated foreign key constraints or triggers.

Item to Be Confirmed and Handling Suggestion

Item to be confirmed: The session_replication_role parameter of the destination database is not set to replica.

Handling suggestion: Before starting the synchronization task, set session_replication_role of the destination database to replica. After the synchronization is complete, change the value of this parameter to origin. If the destination database is an RDS instance, you can modify the parameter on the RDS console.
