![]() ![]() ![]() This method is more time consuming, but you must use this method if you are upgrading from an ArcGIS 10 instance, because there is no direct upgrade path from 10 to 11.1. Migrate content to a new geodatabase in an Amazon relational database service instance.If the geodatabase is already in Amazon Relational Database Service (RDS) for PostgreSQL, Amazon automatically updates the PostgreSQL version therefore, you only need to upgrade the geodatabase after upgrading your ArcGIS software. If it is not, you also must upgrade the PostgreSQL database cluster. If the geodatabase is in a PostgreSQL database cluster on AWS, be sure the existing PostgreSQL version is compatible with the latest version of ArcGIS software. Update the ArcGIS software on the existing Amazon Elastic Compute Cloud (EC2) instance and upgrade the geodatabase.To upgrade an enterprise geodatabase in PostgreSQL on Amazon Web Services (AWS), do one of the following: Upgrade your geodatabases to take advantage of new functionality and improvements implemented in the geodatabase. Migrate content to a 11.1 geodatabase in an Amazon database service instance.Update the ArcGIS software on your existing AWS instance and upgrade the geodatabase.There is no difference in pricing according to the version used. To match updates by the open source community to older PostgreSQL major versions, Amazon Aurora has also announced compatibility and support for 9.6.22, 10.17, 11.12, and 12.7. Version 12 and 13 have been recently added to Azure Database and Google Cloud SQL for PostgreSQL supports version 13 as well as older ones. (.) Earlier versions of PostgreSQL were not as effective in pruning partitions, requiring many queries to scan all partitions.ĪWS is not the only cloud provider offering a managed PostgreSQL 13. (.) One of the key features in PostgreSQL 13 enabling this scale is an improvement in partition pruning. When these tables get large, splitting these tables into many smaller tables will improve database performance and make maintenance much easier. ![]() In a separate article called "Designing high-performance time series data tables on Amazon RDS for PostgreSQL", Jim Mlodgenski, principal database engineer at AWS, and Andy Katz, senior product manager at AWS, explain how table partitioning and partition pruning are more effective in PostgreSQL 13, a critical feature for time series data tables:īy their nature, time series tables grow continuously. Shayon Sanyal, senior database specialist solution architect at AWS, recently presented a webinar about PostgreSQL 13 and the options to run it on AWS. I also know AWS is contributing to PostgreSQL, just like Microsoft is doing. I hope they use more and more of the Open Source PostgreSQL version in the future. For version PG 12, they took 18 months to catch up with the community version. It's interesting to watch AWS shorten the release cycle of Aurora PostgreSQL versions. Jean Baro, senior principal solution architect at Questrade Financial Group, comments: The added support for the latest PostgreSQL version comes a few months after the announcement of supporting PostgreSQL 12 on Amazon Aurora and of PostgreSQL 13 on Amazon RDS. The release adds support for bool_plperl, an extension to write procedures in Perl, and includes new ways to monitor activity within a database, using query sampling, improved WAL usage statistics and new system views. Other benefits and enhancements of running PostgreSQL 13 are incremental sorting to accelerate data sorts, parallel processing of indexes with the VACUUM command and new security capabilities. The compatibility with the latest major PostgreSQL version adds improvements such as higher performing partitioned table queries and deduplication of B-tree index entries. AWS has recently announced that Amazon Aurora supports major version 13 of PostgreSQL.
