PostgreSQL
Query and update PostgreSQL databases. Run SQL safely from your agent.
Details
PostgreSQL skill lets your agent run read and optionally write SQL against a Postgres database. For reporting, lookups, and light ETL.
When to use
Use when the agent should answer questions from your DB or run reports. Restrict to read-only or dedicated role; never expose raw credentials in chat.
How PostgreSQL fits into your OpenClaw setup
Data skills connect OpenClaw to the places your information actually lives — databases, spreadsheets, APIs, and document stores. PostgreSQL belongs to this group, and its value is direct: questions that used to mean writing a query or exporting a report become a sentence in chat.
A typical session
A typical exchange starts with a question in plain language. The assistant translates it into the right query or lookup through PostgreSQL, runs it, and replies with the answer — often with a follow-up suggestion you had not thought to ask. For recurring reports, you can ask the assistant to run the same check on a schedule and post the result to your channel.
Installing PostgreSQL
Installation follows the standard ClawHub flow. From your OpenClaw directory, run the install command below, then restart your assistant so the new capability registers. If the skill needs credentials or API access, its README will say so — set those up before the first use.
Verify the install with a deliberately simple test before relying on it for real work. A thirty-second check separates a skill that is not installed from one that is misconfigured — two failures that look identical from inside a conversation and waste time when discovered late.

Think of PostgreSQL as one instrument in an ensemble. OpenClaw's real strength is composition — the assistant combining several skills in a single task because the request demanded it. When you browse the catalogue, look for the skills that complete your workflows, not just the ones that sound impressive in isolation.
Setting this up well takes judgment as much as effort — which skills, in what configuration, integrated with which of your tools. That is the work we do for clients: full OpenClaw setup, skills like PostgreSQL tuned to your workflow, and custom development where nothing off the shelf fits.
