![]() ![]() Using the awscli provides a good way to clarify the exact upgrades allowed. In this case the table of source, target could be clearer to say something like "Versions from 9.7 and to 10.17 allow to 11.x". $ aws rds describe-db-engine-versions -engine aurora-postgresql -engine-version 10.16 -query 'DBEngineVersions.ValidUpgradeTarget.' -output textĪnnouncement blog posts tend to provide just high level detail and in order to understand gotcha's and workarounds its essential to read the documentation. ![]() Using the cli - we figure out that 10.16 is only upgradable to 11.x What happens if you have version 10.16? It is not in the list and you have to either assume that it is treated the same as version 10.7 OR 10.18 and assumptions are bad.įor example - upgrading to 10.16 to 13.3 fails withĮrror message = Cannot upgrade aurora-postgresql from 10.16 to 13.4 (Service: AmazonRDS Status Code: 400 Error Code: InvalidParameterCombination)įortunately there is a way to figure out which major versions are supported using the aws cli and this is in the same documentation linked above In my opinion that documentation is not very clear. Not so fast though! The devil is in the detail of the source and target version - see this from the linked documentation Upgrade from PostgreSQL 10.X to PostgreSQL 13.X ![]() Upgrade from PostgreSQL 9.6.X to PostgreSQL 12.X OR In that they mention that you could upgrade from Neither option was elegant and has many considerations (like time taken, outages required or even data integrity)ĪWS recently announced that Amazon Aurora supports Multi Major Version Upgrade to Aurora PostgreSQL 11 and higher. OR you resorted to dumping out the entire database and importing it back into a new database with the latest version. You had to upgrade one major version at a time. You then decided to take the opportunity to upgrade all the way to the latest version (version 13). If it requires code change, Microsoft will fix the defect to address the production issue, if possible, and work with the community to incorporate the fix as quickly as possible.Major version upgrades for Aurora PostgreSQL used to be painful if you were behind on versions.įor example - lets assume you were on Aurora PostgreSQL 9.6 and AWS notified users that they are no longer supporting this version. When an defect with PostgreSQL engine is identified, Microsoft will take immediate action to mitigate the issue. Our open source team also incorporates feedback from our Azure fleet (and customers) when prioritizing work, however please keep in mind that Postgres project has its own independent contribution guidelines, review process and release schedule. Our contributions include but aren't limited to features, performance enhancements, bug fixes, security patches among other things. Microsoft has a team of committers and contributors who work full time on the open source Postgres project and are long term members of the community. For example, there's currently no automatic upgrade from PostgreSQL 11 to PostgreSQL 12. Azure Database for PostgreSQL automatically patches servers with minor releases during the service's monthly deployments.Īutomation for major version upgrade isn't yet supported. The PostgreSQL project regularly issues minor releases to fix reported bugs. Please use the Single Server deployment option if you require older versions. We don't support PostgreSQL version 10 and older for Azure Database for PostgreSQL - Flexible Server. Your existing servers will be automatically upgraded to the latest supported minor version in your future scheduled maintenance window. New servers will be created with this minor version. Refer to the PostgreSQL documentation to learn more about improvements and fixes in this release. Think of it as the team’s best practices on how to set up your workstation. The goal is only to provide a step-by-step that can be used to set up a workstation quickly without much prior knowledge. We don’t mean to be dogmatic in this document. Refer to the PostgreSQL documentation to learn more about improvements and fixes in this release. Overview Setting up your workstation is a very personal project.
