This topic describes the limits of RDS PostgreSQL. To guarantee stability and security, you must understand the limits.
The following table describes the limits of RDS PostgreSQL.
|Database root permission||RDS does not offer the superuser permission.|
|Build database replication||PostgreSQL provides a dual-node cluster based on the master/slave replication architecture(except for the basic edition). The slave instance in the architecture is invisible to you, and your application cannot access to the slave instance directly.|
|Restart the RDS instance||The instance must be restarted through the RDS console or OpenAPI.|
