PostgreSQL 12: Partitioning is now faster

September 17, 2019/4 Comments/in 2ndQuadrant, David's PlanetPostgreSQL /by David Rowley

Table partitioning has been evolving since the feature was added to PostgreSQL in version 10. Version 11 saw some vast improvements, as I mentioned in a previous blog post. During the PostgreSQL 12 development cycle, there was a big focus on scaling partitioning to make it not only perform better, but perform better with a […]

Partitioning enhancements in PostgreSQL 12

July 15, 2019/1 Comment/in 2ndQuadrant, Kirk’s PlanetPostgreSQL /by Kirk Roybal

June 9, 2017/0 Comments/in Shaun's PlanetPostgreSQL /by Shaun Thomas

With the christening of PG Phriday at its new location, it’s only fitting that we revisit a frequent boon and bane of organized storage: partitioning.
