Lessons from the Road: What actually matters
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.
Part 6: Prevention and Monitoring Strategies
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.
Lessons from the Road: Gratitude
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.
“I …
Part 5: Temp Tables and XID Wraparound in Single-DB Clusters
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.
Lessons from the Road: Know your footprint
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: Debugging Limitations in RDS and Cloud Environments
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.

Part 3: Why Autovacuum Stops — PostgreSQL Internal Mechanics Explained
Series Summary: This is Part 3 of a multi-part series on PostgreSQL autovacuum failures.
In Part 2, we reproduced the autovacuum failure issue — now let’s understand why it happens. This post dives into PostgreSQL internals, explaining how autovacuum allocates its resources and why certain databases get “stuck” in maintenance limbo.
Why Does This Occur?
This behavior stems from how the autovacuum daemon allocates its resources. Autovacuum identifies the …
