About
Make PostgreSQLfeel easier.
Understand it. Troubleshoot it. Prepare for interviews. Find a PostgreSQL role. One place.
What exists now
The library, as it is.
102 errors, 105 runbooks, 37 lessons, 34 deep internals. Interview prep ships as it does today. Jobs is a curated snapshot.
Errors
SQLSTATE pages. Cause, fix, and captured lab output. Cited to the manual.
Runbooks
Incident playbooks. What to check, in order, when something is on fire.
Lessons
Internals, taught as a course. Mechanism first, then the operator move.
Interview
Senior-loop questions and concept drills. The interview-prep that ships today.
Jobs
A live curated snapshot of PostgreSQL roles. Automated crawl is off.
How we build
Lab, then the manual.
We run it in a lab. Then we cite the manual. Not vibes. Not unaudited summaries.
01
Reproduce it
Spin up PostgreSQL. Trigger the failure. Capture the raw output.
02
Cite it
Explain the cause and the fix from the official PostgreSQL manual.
How it started
Four beats. No origin myth.
