Syed Salman Ahmed Bokhari: Setting Up a PostgreSQL 3-Node HA Cluster using pg_cirrus
Introduction We are thrilled to announce the release of pg_cirrus! First of all, you might be wondering what “cirrus” means. The term refers to the thin and wispy clouds that are often seen at high altitudes. pg_cirrus is a simple and automated solution to deploy highly available 3-node PostgreSQL clusters with auto failover. It is […]

Michael Christofides: Database change management vs performance
This month’s PGSQL Phriday topic is “database change management”, proposed by Dian Fay.
While I’ll try to make this topic about performance (as I always do) let me first embark on a quick trip down memory lane.

Grant Fritchey: PGSQL Phriday #009: On Rollback
The invitation this month for #PGSqlPhriday comes from Dian Fay. The topic is pretty simple, database change management. Now, I may have, once or twice, spoken about database change management, database DevOps, automating deployments, and all that sort of thing. Maybe. Once or twice. OK. This is my topic. I’ve got some great examples on […]

Maxim Boguk: Please welcome Pg_index_watch – a utility for dealing with index bloat on frequently updated tables.
One of the big topics in Postgres is bloat. It is something that every DBA comes across and in fact we have a few good posts on how to work with bloat in our blog.
Update-heavy tables is a special case of data that due to business requirements needs to be updated frequently to stay relevant. Autovacuum may be a good solution for table bloat (you can check this post describing how to do that), however it does not help with index bloat.

Dian Fay: PGSQL Phriday #009: Three Big Ideas in Schema Evolution
I've used several migration frameworks in my time. Most have been variations on a common theme dating back lo these past fifteen-twenty years: an ordered directory of SQL scripts with an in-database registry table recording those which have been executed. The good ones checksum each script and validate them every run to make sure nobody's trying to change the old files out from under you. But I've run into three so far, and used two in production, that do something different.
Roberto Mello: Logical Replication on Standbys in Postgres 16

Umair Shahid: Data inconsistency in highly available PostgreSQL clusters
If nodes in a database cluster get out of sync, the inconsistency can cause data corruption. This blog describes what to watch out for.
The post Data inconsistency in highly available PostgreSQL clusters appeared first on Stormatics.
Martin Davis: SVG Images from Postgres
PostGIS excels at storing, manipulating and analyzing geospatial data. At some point it's usually desired to convert raw spatial data into a two-dimensional representation to utilize the integrative capabilities of the human visual cortex. In other words, to see things on a map.

Laurenz Albe: ERROR: invalid byte sequence – Fix bad encoding in PostgreSQL
It’s annoying to get error messages caused by encoding problems. But it is more annoying not to get error messages and end up with bad data in the database. I’ll show you how to fix bad encoding.

Disaster recovery is not optional for businesses operating in the digital age. With the ever-increasing reliance on data, system outages or data loss can be catastrophic, causing significant business disruptions and financial losses.
