The Varchar Blues: A Database Migration Noir

December 31, 2025 | By Nick Holloway, Private Investigator

The database was as corrupt as a two-bit politician at a campaign fundraiser. Somewhere in the dark corners of PostgreSQL, a varchar(50) constraint was lurking like a snitch in a speakeasy, just waiting to rat out anyone who dared speak more than fifty characters.

It started innocent enough. Ten literary personas—Christie, Hammett, Highsmith, the whole crew—ready to teach an AI how the masters did it. But when you try to explain Patricia Highsmith's psychological depth in under fifty characters, you're going to have a bad time. The database threw an error that would've made a grown DBA weep into their cold coffee.

22001: value too long for type character varying(50)

That's database-speak for "nice try, chump."

The Investigation

I lit a cigarette and started digging. The EF Core model said text—unlimited, wide open, free as a bird. The migrations said text. Even the model snapshot, that lying witness, swore up and down it was text. But the actual database? That dame was wearing varchar(50) like a bad disguise at a masquerade ball.

Schema drift. The oldest story in the DevOps playbook. Someone, somewhere, at some time, had modified the database by hand. Maybe they meant well. Maybe they were trying to save disk space. Or maybe they just liked watching developers suffer. I've stopped asking why people do the things they do.

The Fix

The solution was cleaner than a newly mopped crime scene:

ALTER TABLE personas ALTER COLUMN name TYPE text;
ALTER TABLE personas ALTER COLUMN description TYPE text;
ALTER TABLE personas ALTER COLUMN tone TYPE text;
ALTER TABLE personas ALTER COLUMN style_guidelines TYPE text;
ALTER TABLE personas ALTER COLUMN example_output TYPE text;

Five lines. Five columns. One migration to rule them all. I wrapped it up in a migration file called FixPersonaFieldLengths and shipped it off to CI/CD like evidence to the district attorney's office. Let them sort it out.

The Certificate Caper

But the night wasn't over. Never is.

Word came down that the SSL certificate on devlin.vining.club wasn't working. I've heard that one before. Usually means cert-manager is asleep at the wheel, or Let's Encrypt decided to take a coffee break. I cracked my knuckles and dove in.

Turns out, the certificate was fine. Perfect, even. Valid until March 2026, issued by Let's Encrypt's R12 intermediate, verification passing like a straight-A student. The certificate was as legitimate as they come.

The real problem? HTTP wasn't redirecting to HTTPS. The site was serving content over both protocols like a two-timing lover. Insecure. Messy. The kind of setup that makes security auditors start reaching for their red pens.

The Redirect Middleware

I created a Traefik middleware that did one thing and did it well: grabbed every HTTP request by the collar and shoved it toward HTTPS like a bouncer at a velvet rope club.

apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
  name: homepage-production-https-redirect
spec:
  redirectScheme:
    scheme: https
    permanent: true

HTTP 301. Permanent redirect. No arguments, no negotiations. Just HTTPS or the highway.

Updated the ingress, committed the code, pushed to GitLab. The CI/CD pipeline would handle the rest. I don't babysit deployments. I've got better things to do.

The Cleanup

The homepage was still hawking two blog posts that didn't exist. "Why .NET 10 Rocks" and "Automating Everything"—both phantom content, promises without substance. Digital vaporware. I deleted those links faster than a witness changes their story.

One blog post remained: "Setting up a K8s Homelab." At least that one had the decency to actually exist.

The End

By the time the sun came up, the work was done. Ten personas living in unlimited text fields. HTTPS redirects keeping the traffic secure. A homepage that only promised what it could deliver.

The database hummed along quietly, and the certificates checked out clean. In this business, that's about as close to a happy ending as you're going to get.

I closed my terminal and poured another cup of coffee. Outside, the city sprawled under a gray sky, full of servers that needed patching, schemas that needed fixing, and bugs that wouldn't find themselves.

But that's tomorrow's problem.

Tonight, the code compiled clean, the tests passed green, and the migrations ran smooth. In the gritty world of DevOps, you take your wins where you can get them.
