Crunchy Data has recently announced an update to the CIS PostgreSQL Benchmark by the Center for Internet Security , a nonprofit organization that provides publications around standards and best practices for securing technologies systems. This newly published CIS PostgreSQL 12 Benchmark joins the existing CIS Benchmarks for PostgreSQL 9.5, 9.6, 10, and 11 while continuing to build upon Crunchy Data's efforts with the PostgreSQL Security Technical Implementation Guide (PostgreSQL STIG )....

UPDATE : Read the updated " How to Setup PostgreSQL Monitoring in Kubernetes " which is even easier to set up and provides additional monitoring features! The open source PostgreSQL Operator provides many features that are required to run a production database-as-a-service on Kubernetes , including provisioning PostgreSQL clusters, performing backup and restore operations , and manage high-availability runtime environments. This time, we are going to look at a very important part of managing...

As you can see from my previous blogs ( A Guide to Building an Active-Active PostgreSQL Cluster ) I’m interested in the ways that we can replicate data in PostgreSQL. For this post, I've decided to write about a product that enabled replicating heterogeneous databases. Through my involvement in the PostgreSQL JDBC project, I’ve had the opportunity to help out the folks in the Debezium project. Debezium is more than just another heterogeneous replication solution. Debezium is built upon the Ap...

Where are you? Go ahead and figure out your answer, I'll wait. No matter what your answer, whether you said "sitting in my office chair" or "500 meters south-west of city hall" or "48.43° north by 123.36° west", you expressed your location relative to something else, whether that thing was your office layout, your city, or Greenwich . A geospatial database like PostGIS has to have able to convert between these different reference frames, known as "coordinate reference systems". The math for the...

PostgreSQL 12, the latest version of the "world's most advanced open source relational database," is being released in the next few weeks, barring any setbacks. This follows the project's cadence of providing a raft of new database features once a year, which is quite frankly, amazing and one of the reasons why I wanted to be involved in the PostgreSQL community. In my opinion, and this is a departure from previous years, PostgreSQL 12 does not contain one or two single features that everyone c...

While PostGIS includes lots of algorithms and functionality we have built ourselves, it also adds geospatial smarts to PostgreSQL by linking in specialized libraries to handle particular problems: • Proj for coordinate reference support; • GDAL for raster functions and formats; • GEOS for computational geometry (basic operations); • CGAL for more computational geometry (3D operations); and • for format support, libxml2, libjsonc, libprotobuf-c Proj for coordinate reference support; GDAL...

Parallel query has been a part of PostgreSQL since 2016 with the release of version 9.6 and in theory PostGIS should have been benefiting from parallelism ever since. In practice, the complex nature of PostGIS has meant that very few queries would parallelize under normal operating configurations -- they could only be forced to parallelize using oddball configurations . With PostgreSQL 12 and PostGIS 3, parallel query plans will be generated and executed far more often, because of changes t...

With the availability of MVT tile format in PostGIS via ST_AsMVT() , more and more people are generating tiles directly from the database. Doing so usually involves a couple common steps: • exposing a tiled web map API over HTTP • converting tile coordinates to ground coordinates to drive tile generation exposing a tiled web map API over HTTP converting tile coordinates to ground coordinates to drive tile generation Tile coordinates consist of three values: • zoom , the level of the tile...
