For information specific to PostgreSQL, see the\n[PostgreSQL documentation](https://www.postgresql.org/docs/).\n\nFeatures\n--------\n\nCloud SQL provides extensive [documentation](/sql/docs). If you're\nnew to Cloud SQL for PostgreSQL, then be sure to check out the\n[Cloud SQL for PostgreSQL features](/sql/docs/postgres/features) page.\n\nInstance settings\n-----------------\n\nMany configuration settings go into the creation of a Cloud SQL instance.\nYour needs may vary from the defaults.\nSee the [Creating instances](/sql/docs/postgres/create-instance)\nand [Instance settings](/sql/docs/postgres/instance-settings) pages for\nmore information.\n\nConnectivity\n------------\n\nCloud SQL offers [connectivity](/sql/docs/postgres/connect-overview)\nthrough [public](/sql/docs/postgres/configure-ip) IP addresses,\n[private](/sql/docs/postgres/configure-private-ip) IP addresses, or both\npublic and private addresses.\n\nFor Database Migration Service, the\n[IP allowlist](/database-migration/docs/postgres/configure-connectivity-ip-allowlists)\nconnectivity method is appropriate when using a public IP address, and the\n[VPC peering](/database-migration/docs/postgres/configure-connectivity-vpc-peering)\nconnectivity method is used for private IP addresses.\n\nCloud SQL recommends using [SSL/TLS\ncertificates](/sql/docs/postgres/authorize-ssl) when connecting to a Cloud SQL instance.\n\nCloud SQL users\n---------------\n\nThe first time you connect to a new Cloud SQL instance, use the\n`postgres` account.\n\nBecause it's a managed service, Cloud SQL doesn't allow PostgreSQL users to have\n`SUPER` privileges.\n\nCascading read replicas\n-----------------------\n\nDatabase Migration Service lets you migrate data to a Cloud SQL destination instance,\nand then set up cascading read replicas for that instance. For more information,\nsee [Set up cascading read replicas](/database-migration/docs/postgres/set-up-cascading-replica).\n\nHigh availability\n-----------------\n\nAfter you [promote](/database-migration/docs/postgres/promote-migration)\na Cloud SQL replica to become a primary instance, you can configure it for\n[high availability (HA)](/sql/docs/postgres/high-availability). If your\nHA-configured instance becomes unresponsive, then Cloud SQL automatically\nswitches to serving data from a standby instance.\n\nWhat's next\n-----------\n\nLearn more about [everything you can do](/sql/docs/postgres/how-to)\nwith your Cloud SQL instance."]]
