The 2015 Gartner Magic Quadrant for Operational Database Management Systems is now available and reflects several important trends and interesting market changes.
One of the most significant changes is the continued movement of open source databases, like EDB Postgres, into the Leaders quadrant alongside giant proprietary vendors like Oracle, Microsoft and IBM.
In fact, Gartner reports that by 2018, 70% of all new applications and 50% of all existing applications will be moved to open source relational databases like EDB Postgres. 

Further, Gartner reports the performance of opens source is now at parity with commercial options but with dramatic total cost of ownership advantages. is a partner of EDB. Please contact us for more information.

A little reminder of why #statistics matter, and how to #tune your #PostgreSQL instance.

Thomas Vondra writes a good recap of why statistics matter in tuning a PostgreSQL instance: "That however does not mean there are no issues with data distribution (planner) statistics, and as that's one of my areas of interest, in this post I'll discuss the usual issues with data distribution statistics, usually observed by the user as slow (or even failing) queries. And I'll also mention what are the possible remedies available (if any)." Common issues with planner statistics

The beautiful possibilities of #Quantum computing #pg_rewind

Interesting article on pg_rewind from Andrea Scherbaum

“Someone in the audience asked, if it’s possible to roll a PostgreSQL database forward, ahead of the master. The answer was that currently it’s not possible, but there is no technical reason why this should not work. So I decided to have a look. Turns out, it’s surprisingly easy to do…”
