PostgreSQL 11: Partitioning Evolution from Postgres 9.6 to 11

October 24, 2018/0 Comments/in 2ndQuadrant, David's PlanetPostgreSQL /by David Rowley

During the PostgreSQL 11 development cycle an impressive amount of work was done to improve table partitioning. Table partitioning is a feature that has existed in PostgreSQL for quite a long time, but it really wasn’t until version 10 that it started to become a highly useful feature. We’d previously claimed that table inheritance was […]

Adding new table columns with default values in PostgreSQL 11

October 18, 2018/3 Comments/in 2ndQuadrant, Andrew's PlanetPostgreSQL /by Andrew Dunstan

In PostgreSQL version 10 or less, if you add a new column to a table without specifying a default value then no change is made to the actual values stored. Any existing row will just fill in a NULL for that column. But if you specify a default value, the entire table gets rewritten with […]

Partitioning Improvements in PostgreSQL 11

September 19, 2018/6 Comments/in Alvaro's PlanetPostgreSQL, PostgreSQL /by Álvaro Herrera

A partitioning system in PostgreSQL was first added in PostgreSQL 8.1 by 2ndQuadrant founder Simon Riggs. It was based on relation inheritance and used a novel technique to exclude tables from being scanned by a query, called “constraint exclusion”. While it was a huge step forward at the time, it is nowadays seen as cumbersome […]

Upgrading to PostgreSQL 11 with Logical Replication

September 6, 2018/8 Comments/in 2ndQuadrant, Eisentraut's PlanetPostgreSQL, PostgreSQL /by Peter Eisentraut

It’s time. About a year ago, we published PostgreSQL 10 with support for native logical replication. One of the uses of logical replication is to allow low- or no-downtime upgrading between PostgreSQL major versions. Until now, PostgreSQL 10 was the only PostgreSQL release with native logical replication, so there weren’t many opportunities for upgrading in […]
