Citus 11 for Postgres Goes Fully Open Source — Citus, a Postgres extension for horizontal scaling, was first open sourced six years ago but with the common business model of offering an extended ‘enterprise’ version for money. No longer. Now there’s only one Citus version and it’s all open source, so features like tenant isolation, non-blocking shard rebalancing, and others are now open to all. This is a huge release and well explained in this post.

The Dalibo Postgres Execution Plan Visualizer — Give this the output from EXPLAIN ANALYZE and get a better view at what Postgres plans to do with your query. Along similar lines to the better known explain.depesz.com but presents the results in a rather different way, so it’s worth trying both.
