To ensure the instance stability and security, the RDS for PPAS has some restrictions on use. See the following details:
|Operations||RDS restrictions on use|
|Modifying database parameter settings||Not supported for the time being|
|Database root permission||RDS cannot provide the superuser permission to you.|
|Database backup||You can back up data only through pg_dump.|
|Data migration||The data backed up by pg_dump can only be restored through psql.|
|Setting up database replication||You do not need to set up the data replication since the system has automatically set up the PPAS stream replication based HA mode.
The PPAS Standby nodes are invisible to you, and cannot be used directly for access.
|Restarting an RDS instance||You must restart an instance through the RDS Console or the OPEN API.|
