Use when needing to query a PostgreSQL database in DEV or PROD, check if records exist, count rows, inspect data, or run read-only SQL queries from within the cluster.
Use when needing to query a PostgreSQL database in DEV or PROD, check if records exist, count rows, inspect data, or run read-only SQL queries from within the cluster.
Use when user says "consulta la BD", "query", "busca en la tabla", "check database", "db query", or "existe este registro".

Database Queries
Overview
Execute read-only SQL queries against PostgreSQL databases via PgBouncer from within application pods. No psql available — use the pg module via node -e.
Configuration
Read project-specific values from the project's CLAUDE.md (## Infrastructure section):
kubectl context, namespace, app pod label, database name, config file per environment
Constraints
PgBouncer does NOT support parameterized queries — use inline SQL with quoted values.
Read-only only. Never run INSERT/UPDATE/DELETE without explicit user confirmation.
Use require('/app/node_modules/pg') — module is not in the global node path.
Use development.config.js for DEV, production.config.js for PROD (both files exist in every pod).
Process
Read the project CLAUDE.md for connection details (context, namespace, db name, pod label)
Find a running pod: kubectl --context=<ctx> get pods -n <namespace> | grep <app-label>
Get connection details from the config file inside the pod
Run the query using the helper script or inline node -e
See [scripts/query.js](scripts/query.js) for the reusable helper (copy to pod with kubectl cp). See [references/query-examples.md](references/query-examples.md) for command templates.
Common Mistakes
Mistake
Prevention
Not reading CLAUDE.md
Namespace, context, DB name vary per project.
Parameterized queries ($1::uuid[])
PgBouncer rejects them. Use inline SQL.
require('pg') fails
Use require('/app/node_modules/pg').
Wrong config file
production.config.js in a DEV pod points to PROD db. Use development.config.js for DEV.
