New Production Plans for More Flexible Scaling To take a look at which of your Heroku Postgres databases can take advantage of PGX Plans now and how, go to. Underneath the hood, we've upgraded the CPU, memory, storage, and networking aspects to ensure your Postgres database is running smoothly at scale. PGX Plans are generally available as of today, and all new Postgres databases will be created on our latest generation of Postgres infrastructure. PGX Plans introduce larger database sizes, more generous resource allocations, and a broader set of options to suit your needs and to help your applications scale more smoothly. These plans are the first component of Heroku Postgres PGX, the next generation of our managed Postgres solution. Today, we’re excited to announce a major update to Heroku Postgres with a new lineup of production plans. If you want to try out the new version, provision a new database: $ heroku addons:create heroku-postgresql -a sushiįor further details about other new features in PostgreSQL 12, please see the PostgreSQL documentation.Posted by Camille Baldock January 17, 2018 Note the changes made to CTE materialization too. Please make sure your database is capable of migrating to supported features before attempting to upgrade to PostgreSQL 12. There are some breaking changes introduced into PostgreSQL. There are a few limitations to consider when examining this new feature, so please be sure to read the new documentation to find new ways to optimize and save space on your database. This enables columns to be computed from other columns when read and can be utilized similar to materialized views using the STORED keyword. With space being the chief commodity in databases, we are excited for the introduction of Generated Columns to PostgreSQL 12. In some cases, column data may be helpful during relational or informational operations. Additionally, VACUUM operations for these indexes were hardened to clean up more space as data changes in the underlying tables occur, maintaining performance and reducing space costs for your PostgreSQL database. GiST, GIN, and SP-GiST indexes have been updated to require less WAL and disk overhead usage during their creation. When users need to alter their indexing structures, pg_stat_progress_create_index progress function shows CREATE and REINDEX operations progress.įor customers using full-text searching or natural clustered data indexing, PostgreSQL 12 writes less information to the Write-Ahead Logs during index creation. Indexing is a crucial performance component of PostgreSQL, so we are excited to see PostgreSQL add REINDEX CONCURRENTLY options for all indexes that no longer block writes to tables. ![]() New features include allowing tables to modify partitions without blocking queries, allowing foreign keys to reference partitioned tables, and adding introspection functions to understand partitioned tables through their lifecycle. Updating tables, altering partitions blocking queries, and executing concurrent operations for Native Partitioning were all improved in PostgreSQL 12. Native Partitioning was introduced in PostgreSQL 10 and performance improvements for improved parallel processing were added in PostgreSQL 11. I want to emphasize a few key changes and improvements in Postgres 12: Native Table Partitioning Concurrent Operations Product Management Director, Heroku Data February 04, 2020Īfter a successful evaluation period, PostgreSQL 12 is now the default version for new Heroku Postgres databases and an available upgrade for existing databases.
