Why does my query drop from 3ms to 4 seconds on Tuesday with no deploy?
Szansa
PostgreSQL's query planner re-evaluates execution plans whenever table statistics change, which happens asynchronously through autovacuum and ANALYZE, independent of any code deployment. A batch import, a routine vacuum after deletion, or a gradual shift in data distribution can flip an index scan to a sequential scan overnight, turning a 3ms query into a 4-second one with no error emitted and no deployment in the history. These regressions are invisible in CI because they are driven by statistics state, not code state, and no standard test harness captures plans across different statistics snapshots. Pganalyze and similar tools detect plan flips after they occur in production, but there is no upstream gate that tests query plan stability before a schema change or data migration ships. PostgreSQL proposed the pg_plan_advice contrib module in October 2025 to let operators hint or pin plan
Dlaczego to ważne
Silent query plan regressions are one of the most common causes of unexplained production latency spikes and they remain undetectable until a user reports slowness.
Jak oceniam szansę
Wskaźnik Szansy to mój własny odczyt, a nie pomiar: jak bardzo boli, jak często daje się we znaki i jak niewiele istnieje dziś, by to rozwiązać. Wyższy wynik oznacza, że uważam problem za bardziej warty zbudowania.
Ile bólu sprawia, gdy się pojawia.
Jak często ludzie faktycznie na to trafiają.
Jak mało dobrych narzędzi istnieje dla tego dziś.

Dlaczego oprogramowanie, od którego jesteśmy najbardziej zależni, jest najgorsze w użyciu?
TechData ownership is still effectively zero for most people because of a few structural problems that reinforce each other: **The terms-of-service trap** Every platform you use grants itself a perpetual, irrevocable, sublicensable license to your content. You "agreed" to this to get access. There is no meaningful negotiation -- it is take-it-or-leave-it, and the network effects make leaving it impractical. **Data is not legally property** In most jurisdictions, raw data has no clear property status. Copyright protects creative expression, not facts or behavioral signals. There is no law that says your location history, click patterns, or biometric data is *yours* the way a car or a house is yours. Without property rights, there is no theft, no trespass, no remedy. **GDPR gave access rights, not ownership** Europe's GDPR is the strongest regime in the world and it gives you the right to *access*, *correct*, and *delete* your data. That is closer to a tenant's rights than to ownership. You cannot sell it, license it, or sue if someone profits from it without your consent. **The commercial model depends on the asymmetry** Surveillance-based advertising -- which funds most of the free internet -- only works if users do not extract economic value from their own data. Any genuine data ownership regime would collapse the current business model of Google, Meta, and most data brokers. **What would actually change things** - A statutory property right in personal data (proposed in various US bills, never passed) - Data intermediaries or cooperatives that negotiate collectively on your behalf - Personal data stores (Solid, MyData) -- technically viable, commercially marginal - MiCA-style sectoral regulation extending beyond financial data The honest answer: it has not changed because the entities that profit from the status quo have lobbying power far exceeding that of individual users, and the problem is diffuse enough that collective action is hard.
