Vondra: PostgreSQL development activity
PostgreSQL contributor Tomas Vondra has published a blog post looking at development activity in the project, with data from the late 1990s to today.
Why am I seeing this Ranked on source trust — LWN
It ranks mainly on source trust: LWN is the most reliable outlet we track on this subject, and is the only one on the story so far.
Single-sourced. No second organisation has confirmed it yet.
Link-outLink-out, because only one organisation carries it and no first-party source is on it. Link-out means we point at the publisher and say nothing of our own.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroboration | 0.35 | 0.39 | +0.135 38% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trustleads | 0.25 | 0.85 | +0.212 60% | LWN is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.02 | +0.004 1% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

PostgreSQL contributor Tomas Vondra has published a blog post looking at development activity in the project, with data from the late 1990s to today. We're doing ~50 commits per week, give or take. In ~2010 we were doing maybe 25/week, and the trend seems to be a slow and consistent growth. The monthly average makes the trend a bit easier to spot. Which is good, although there's a lot of other important details (size of commits, are they new features or fixes,...). It however nicely aligns with the number of active committers, which also grew ~2x between 2010 and today.
