## What it does

The skill gives the agent a set of reference files for PostgreSQL 14 through 18. They cover schema design, indexing, query optimization, query patterns, performance diagnostics, logical replication, hot standby, transaction isolation, backup and restore, security and roles, bulk loading, connection pooling, and major version upgrades. The agent opens the file that matches the task at hand.

Version-specific features carry tags like `[PG15+]` and `[PG18+]`. Examples that depend on the environment name the privileges, extensions or multi-node setup they need, so check those before running one.

Install takes a single `npx skills add` command, and the skill lands in your platform's skills folder. It runs in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Requirements
- Works with: PostgreSQL

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add neondatabase/postgres-skills --skill postgres-best-practices -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/postgres-best-practices/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/postgres-best-practices/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add neondatabase/postgres-skills --skill postgres-best-practices -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/postgres-best-practices/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add neondatabase/postgres-skills --skill postgres-best-practices -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/postgres-best-practices/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install neondatabase/postgres-skills postgres-best-practices
```

2. **Manually: put the files in place**
- File: `.github/skills/postgres-best-practices/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add neondatabase/postgres-skills --skill postgres-best-practices -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/neondatabase/postgres-skills --path skills/postgres-best-practices
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/postgres-best-practices/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add neondatabase/postgres-skills --skill postgres-best-practices -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/neondatabase/postgres-skills/tree/HEAD/skills/postgres-best-practices/SKILL.md

## When to use it
- design a table schema for a known workload
- pick the right index type for frequent queries
- read an EXPLAIN ANALYZE plan and find the bottleneck
- configure PgBouncer connection pooling
- plan a major version upgrade

## Example prompts
- check the postgres-best-practices skill for the right index for this query
- review my table schema against postgres-best-practices
- how does postgres-best-practices say to set up PgBouncer for this service

# Postgres Best Practices

Guidelines and best practices for working with Postgres, covering schema design, indexing, query optimization, and common pitfalls.

## Supported Versions

This skill covers PostgreSQL 14 through 18. Version-specific features are tagged (e.g., `[PG15+]`, `[PG18+]`); environment-dependent examples identify required privileges, extensions, or multi-node setup.

PostgreSQL provides 5 years of support per major version. Always run the latest minor release.
