PostgreSQL & RDS triage — Field Kit

Field Kit / PostgreSQL

Scope: PostgreSQL 12–16 · Amazon RDS & Aurora Run this first: SELECT version(); — version and build change which fixes apply.

Fuzzy: typos are fine. SQLSTATE numbers match error codes. The chips below browse by category; the filter above narrows to your environment.

Triage tree

Symptom → cause → numbered fix. Every outcome names the dependencies to check and when to escalate. Jump into any area, or search above for a specific code.

Now — first-responder scripts

Copy-paste diagnostics for "what's happening right now." Comments say where to run each and what healthy looks like. All read-only unless flagged.
