Run PostgreSQL queries for testing, debugging, and performance analysis. Use when you need to query the database directly, run EXPLAIN ANALYZE, compare query results, or test SQL optimizations. Always uses read-only connections unless explicitly directed otherwise.
默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/JSGforever/skillguard --skill postgres-query命令会保持在同一行。复制前请横向滚动并检查完整内容。

Use this skill to run ad-hoc PostgreSQL queries for testing, debugging, and performance analysis.
Use the included query script:
node .claude/skills/postgres-query/query.mjs "SELECT * FROM \"User\" LIMIT 5"
| Flag | Description |
|---|---|
--explain | Run EXPLAIN ANALYZE on the query |
--writable | Use primary database instead of read replica (requires user permission) |
--timeout <s>, -t | Query timeout in seconds (default: 30) |
--file, -f | Read query from a file |
--json | Output results as JSON |
--quiet, -q | Minimal output, only results |
# Simple query
node .claude/skills/postgres-query/query.mjs "SELECT id, username FROM \"User\" LIMIT 5"
# Check query performance
node .claude/skills/postgres-query/query.mjs --explain "SELECT * FROM \"Model\" WHERE id = 1"
# Override default 30s timeout for longer queries
node .claude/skills/postgres-query/query.mjs --timeout 60 "SELECT ... (complex query)"
# Query from file
node .claude/skills/postgres-query/query.mjs -f my-query.sql
# JSON output for processing
node .claude/skills/postgres-query/query.mjs --json "SELECT id, username FROM \"User\" LIMIT 3"
DATABASE_REPLICA_URL to prevent accidental writes--writable flag is used--writable, you MUST ask the user for permissionOnly use the --writable flag when:
IMPORTANT: Always ask the user for permission before running with --writable.
To compare two query approaches:
# Run first approach
node .claude/skills/postgres-query/query.mjs --explain "SELECT ... (approach 1)"
# Run second approach
node .claude/skills/postgres-query/query.mjs --explain "SELECT ... (approach 2)"
# Compare actual results
node .claude/skills/postgres-query/query.mjs --json "SELECT ... (approach 1)" > /tmp/q1.json
node .claude/skills/postgres-query/query.mjs --json "SELECT ... (approach 2)" > /tmp/q2.json
Run with --explain and look for:
node .claude/skills/postgres-query/query.mjs --explain "SELECT * FROM \"Account\" WHERE provider = 'discord'"
