This page describes Cloud SQL's database version support policies.
Major and minor versions supported by Cloud SQL
Cloud SQL supports the following database versions:
Major version | Minor version |
---|---|
PostgreSQL 15 (default) | 15.5 |
PostgreSQL 14 | 14.10 |
PostgreSQL 13 | 13.13 |
PostgreSQL 12 | 12.17 |
PostgreSQL 11 | 11.22 |
PostgreSQL 10 | 10.23 |
PostgreSQL 9.6 | 9.6.24 |
Cloud SQL automatically keeps your instances up to date with patches and minor version updates.
As indicated in the previous table, the database engines supported by Cloud SQL include multiple versions. The versions can vary in their functionality and in the types of issues that arise. While Cloud SQL recognizes that upgrades impact users, we are committed to providing up-to-date functionality and important patches.
Major and minor versions
For PostgreSQL 9.6, the first two numbers in the version number form the major version number. For example, for version 9.6.1, Cloud SQL uses 9.6 as the major version, and 1 as the minor version.
For PostgreSQL 10 and upwards, the first number is the major version number. For example, for version 10.1, 10 is the major version number, and 1 is the minor version.
Major version support
Cloud SQL aims to support new major versions within five months of general availability release by the database engine developer.
Minor version support
Cloud SQL aims to support new minor versions within three months of general availability release by the database engine developer.
Major version deprecation plan
When Cloud SQL intends to end support for a specific major version, we will send a deprecation notice alerting project owners a minimum of 12 months ahead.
Cloud SQL will also provide tools to minimize upgrade disruption, as needed. Any instance that has not moved to the new major version at the end of the 12-month period will be automatically upgraded.
When did Cloud SQL support for each database version begin?
