Install Postgres

skills CLI

$ npx skills add timescale/pg-aiguide --skill postgres -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI

$ gh skill install timescale/pg-aiguide postgres --agent claude-code

What it does

Postgres is an agent skill from timescale/pg-aiguide. Use this skill for any PostgreSQL database work — table design, indexing, data types, constraints, extensions (pgvector, PostGIS, TimescaleDB), search, and migrations. Trigger when user asks to: - Explore an existing PostgreSQL database to understand its objects and relationships - Design or modify PostgreSQL tables, schemas, or data models - Choose data types, constraints, indexes, or partitioning strategies - Work with pgvector embeddings, semantic search, or RAG - Set up full-text search, hybrid search, or…

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files (for example `references/backfill-strategies.md`, `references/complete-example.md` and `references/design-postgis-tables.md`).

It sits in Databases, covering Retrieval-augmented generation, Embeddings and Forecasting and time series. It works with PostgreSQL, pgvector, SQL and Model Context Protocol. The repository describes itself as: MCP server and Claude plugin for Postgres skills and documentation. Helps AI coding tools generate better PostgreSQL code. The licence is Apache-2.0.

When your agent uses it

Any PostgreSQL database work — table design
Extensions (pgvector
User asks to: - Explore an existing PostgreSQL database to understand its objects and relationships - Design
Modify PostgreSQL tables

Example prompts

“/postgres”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Identify which reference matches the user's task from the descriptions above.
Load the reference file to get detailed instructions and SQL patterns.
For tasks spanning multiple areas (e.g., "design a table with vector search"), load multiple references as needed.

What it can do on your machine

Read from SKILL.md and the folder at commit b236d35. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Postgres loads about 941 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 238 tokens; SKILL.md has 263 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~238
When it runs · the whole SKILL.md, loaded when a task matches: ~941
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Questions about Postgres

What does Postgres do?

A skill your agent uses for any PostgreSQL database work — table design, indexing, data types, constraints, extensions (pgvector, PostGIS, TimescaleDB), search, and migrations. Postgres is an agent skill from timescale/pg-aiguide. Use this skill for any PostgreSQL database work — table design, indexing, data types, constraints, extensions (pgvector, PostGIS, TimescaleDB), search, and migrations.

When should I use Postgres?

Postgres fits situations like: any PostgreSQL database work — table design; extensions (pgvector; user asks to: - Explore an existing PostgreSQL database to understand its objects and relationships - Design; modify PostgreSQL tables.

How do I install Postgres in Claude Code?

Run `npx skills add timescale/pg-aiguide --skill postgres -a claude-code`. Or copy the skill folder (skills/postgres in timescale/pg-aiguide) into .claude/skills/postgres in your project. Claude Code loads it when a task matches its description.

How do I install Postgres in Codex?

Run `npx skills add timescale/pg-aiguide --skill postgres -a codex`. Or copy the skill folder (skills/postgres in timescale/pg-aiguide) into .agents/skills/postgres in your project. Codex loads it when a task matches its description.

Can I use Postgres in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add timescale/pg-aiguide --skill postgres -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/postgres, .gemini/skills/postgres, .github/skills/postgres and .opencode/skills/postgres in your project.

What does Postgres need to run?

SKILL.md names no scripts, command-line tools or credentials: Postgres is instructions for the agent only.

Does Postgres access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Postgres safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Postgres use?

Postgres is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Postgres use?

About 941 tokens (SKILL.md is roughly 3.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 152 tokens, read only when the agent opens those files.

What are the alternatives to Postgres?

Skills that share tags, products or a category with Postgres: Searching Documents (GAIK-project/gaik-toolkit, 100 stars), Neon Postgres (usenotra/notra, 255 stars), Mindsdb MCP Skill (LeoYeAI/openclaw-master-skills, 2.2k stars) and Vsql Install Server (hashgraph-online/awesome-codex-plugins, 1.2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Postgres?

timescale (a GitHub organization) maintains it in timescale/pg-aiguide, which has 1,857 GitHub stars. The repository holds 9 skills in this directory. The repository was last updated on October 1, 2026.

Source: timescale/pg-aiguide on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
