This page describes the major features and capabilities of Google Cloud SQL for PostgreSQL. Cloud SQL is also available for MySQL.
Cloud SQL for PostgreSQL
You can use Google Cloud SQL for PostgreSQL with App Engine applications running in the flexible environment that are written in Java, Python, PHP, Node.js, Go, and Ruby. You can also use Cloud SQL for PostgreSQL with external applications using the standard PostgreSQL client-server protocol.

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.
Any features that require
An exception to this rule is made for the
CREATE EXTENSIONstatement, but only for supported extensions.
Custom background workers
psqlclient in the Cloud Shell does not support operations that require a reconnection, such as connecting to a different database using the
