To ensure instance stability and security, the RDS for PostgreSQL has some restrictions, as detailed below:

Operations RDS Restrictions
Modifying database parameter settings Currently not supported
Database root permission Cannot provide the superuser permission
Database backup Data backup can only be performed through pg_dump
Data migration Data backed up by pg_dump can only be restored through psql
Building database replication The system automatically builds the HA mode based on PostgreSQL stream replication.
The PostgreSQL Standby node is invisible and cannot be accessed directly
Restarting the RDS instance The instance must be restarted through the RDS console or OPEN API
