Fixes dbt-postgres failures where remaining connection slots are reserved for superuser, meaning the server connection limit is exhausted. Use when dbt cannot open new Postgres connections. Not for authentication failures on an otherwise reachable server.
Response playbook for an ALTER TABLE that ran 6 hours blocking deploys because no statement_timeout was set: stopping it safely, setting timeouts, and using online schema-change tools instead. Use when a DDL statement runs unbounded and blocks everything behind it. Not for slow DML or stuck queries.
Prevents EXPLAIN ANALYZE on write queries in production with safe alternatives. Use after an accidental production write from EXPLAIN. Key trigger: a write query executed via EXPLAIN ANALYZE in prod.

Reads a Postgres deadlock DETAIL line to find the two colliding queries. Use when the log shows 'deadlock detected' with waiter and blocker processes. Shows how to map both PIDs to their SQL and fix the lock ordering. Key trigger: DETAIL names a waiter process blocked by another process.
Fixes Supabase pgbouncer pooler timeouts on burst traffic. Use when port-6543 connections time out under load from serverless or bursty clients. Covers confirming pooler use, clearing idle-in-transaction hogs, sizing the pool, and client retries. Key trigger: pooler checkouts time out while direct connections still wo…
