Differences between Cloud SQL and standard PostgreSQL functionality
In general, the PostgreSQL functionality provided by a Cloud SQL instance is the same as the functionality provided by a locally-hosted PostgreSQL instance. However, there are a few differences between a standard PostgreSQL instance and a Cloud SQL for PostgreSQL instance.
Unsupported features
Any features that require
SUPERUSER
privilegesAn exception to this rule is made for the
CREATE EXTENSION
statement, but only for supported extensions.Custom background workers
The
