Checking Details
In PostgreSQL migration scenarios, the target instance cannot contain objects with the same names as those in the source database.
If tables and views with the same names as the objects to be migrated exist in the target, the task will report an error.
If functions, triggers, and indexes with the same names as the objects to be migrated exist in the target, the task will report an error.
During the migration of an entire PostgreSQL instance, the target instance must be empty.
Fixing Methods
If a conflict is detected, delete the conflicting content or rename the conflicting objects, and then initiate the check task again.
