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