SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It prevents fragile PostgreSQL schema and migration work by turning changes into production-safe database slices with explicit evidence, rollback discipline, and operational readiness.

Core Features & Use Cases

  • Schema, index, and migration planning with verification evidence: defines data contracts, designs indexes from query shapes, and requires EXPLAIN (ANALYZE, BUFFERS)-style proof for hot-query changes.
  • Online, mixed-version compatible deployment sequences: sequences deploy steps using lock-minimizing patterns like CONCURRENTLY indexes, NOT VALID constraints, batched backfills, and validation phases.
  • Operational and rollback concrete requirements: budgets lock impact and WAL/replica-lag effects, names restore points/PITR feasibility, and specifies rollback triggers and observability for locks, deadlocks, and replication lag.

Quick Start

Use postgres-domain-delivery to implement or review the Postgres migration for your target change while capturing the smallest scoped evidence and a reversible rollback path.

FAQPage Schema
How do I run safe PostgreSQL migrations without locking tables in production?▼

PostgreSQL rollback discipline requires naming concrete restore points, verifying PITR feasibility, and defining explicit rollback triggers alongside observability for locks, deadlocks, and replication lag before deploying changes.

How do I verify a PostgreSQL index strategy actually improves query performance?▼

You verify a PostgreSQL index strategy by gathering explicit evidence from local source-of-truth using query-plan inspection, requiring EXPLAIN (ANALYZE, BUFFERS)-style proof to validate index designs against actual hot-query shapes.

What is transaction isolation's role when planning reversible PostgreSQL schema changes?▼

Transaction isolation semantics ensure PostgreSQL schema changes maintain data consistency during mixed-version deployments, requiring explicit verification evidence and structured PASS/PARTIAL/BLOCKED status output to confirm operational readiness.

How do I plan PostgreSQL backfill deployments that minimize WAL and replica lag?▼

Plan PostgreSQL backfill deployments using batched processing sequences that budget WAL and replica-lag effects, incorporating validation phases and operational observability to monitor replication-sensitive changes throughout execution.

When should I not use CONCURRENTLY for PostgreSQL index creation?▼

You should avoid CONCURRENTLY index creation when operating under strict transaction isolation constraints or when query-plan inspection reveals incompatible locking patterns, requiring structured BLOCKED status output instead of proceeding.
