Discover how a client successfully upgraded PostgreSQL 11 to 15.5 and Citus 8.3 to 12.1 while simplifying extensions, improving scalability, and enhancing performance. This real-world case study highlights the planning, testing, and expertise required to achieve seamless upgrades in distributed environments.
How much of our time is spent on autopilot?
Most people can agree that our internal autopilot systems enable us to be efficient and effective. It allows us to do things like listen to a client while trying to find the bug they are describing in the source code. Or make dinner while holding a conversation. Or even have Spiderman-like reflexes when a child falls out of a chair across …
A modern approach to IT observability inspired by hazard analysis. Learn how to improve system reliability, reduce monitoring complexity, and proactively manage service risks through Critical Control Points.
A critical, newly disclosed, and actively exploited vulnerability, CVE-2025-53770, affects all self-hosted / on-premises Microsoft SharePoint Server versions. This critical issue does not impact SharePoint Online (Microsoft 365).

Amid life's many demands, what truly matters? Inspired by her sister‑in‑law’s final words—"It is well"—Amanda Nystrom invites us to define what it means to live without regret.
PostgreSQL’s autovacuum is a silent guardian until it fails. In this final post of our autovacuum series, we tackle two often-overlooked scenarios that can lead to database downtime: temp tables in multi-database clusters and lingering sessions with temp tables. Learn practical prevention tactics and monitoring strategies to keep your cluster safe from XID wraparound and emergency shutdowns.
I was on the phone with one of my most active clients at Command Prompt when I had to interrupt the call because my dogs somehow opened the bus door and went running after horses. The client and Command Prompt have a good relationship so I wasn’t too worried about the fallout. However, what the client said when I returned to the call and explained the interruption was surprising.
Even in single-database setups, temp tables can quietly lead to major problems. In this post, we break down how long-lived temp tables contribute to XID wraparound risk, why PostgreSQL shuts down to protect against it, and what proactive steps you can take to avoid unexpected downtime.
What is the weight of your footprint?
What is the cost of your footprint?
One of the most surprising things I experience when I go from a house to a school bus is the sheer amount of waste we as humans produce. From packaging to paper towels to food scraps to everything else I won’t mention here, it’s a lot. When I am stationary at home, my trash hides …
Part 4 of our PostgreSQL Autovacuum Failure Series explores how session-level temp tables in RDS can silently stall autovacuum—and how we resolved it. Learn why monitoring and visibility are critical in managed cloud environments.
