Keep your libraries updated and nobody gets hurt

May 14, 2020/0 Comments/in Jimmy's Planet PostgreSQL /by Jimmy Angelakos

Don’t make people practice software archaeology – keep your system updated. Updates? One of the benefits of the open-source world is the unmatched ability to issue updates rapidly to correct bugs and security vulnerabilities. Software bug fixes keep streaming in: from recently introduced regressions, to long-standing bugs undetected for years, they are corrected by a […]

January 3, 2019/0 Comments/in 2ndQuadrant, Liaqat's PlanetPostgreSQL, PostgreSQL /by Liaqat Andrabi

After the final release of patch 9.3.25 on November 8th 2018, PostgreSQL 9.3 is no longer supported.

September 6, 2018/7 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.
