Infra Postgres Agent Skill
Sets up and manages Postgres using the clickhousectl CLI — runs a local Docker-backed Postgres for development, and creates and operates managed ClickHouse Cloud Postgres services (connections, TLS, runtime config, read replicas, failover, point-in-time restore). Use when the user wants a Postgres or PostgreSQL database for their application, a local Postgres dev environment, psql access, or a managed/production Postgres in ClickHouse Cloud, or mentions moving a local Postgres to production.

4 sections, as written by the authorPostgres with clickhousectl
clickhousectl manages Postgres in two environments:
- Local — named, Docker-backed Postgres instances on the user's machine, for development.
- Cloud — managed Postgres services in ClickHouse Cloud (beta), for production: HA, read replicas, point-in-time restore.
This file routes to the right reference. The step-by-step workflows live in ref/local.md and ref/cloud.md — read the one that matches the user's situation before running commands.
Which reference to use
| The user wants to... | Read |
|----------------------|------|
| Develop or prototype locally, run tests/CI against Postgres, no cloud account needed | ref/local.md |
| Go to production, host a managed Postgres, or use ClickHouse Cloud explicitly | ref/cloud.md |
| Operate an existing cloud service (passwords, TLS, config, replicas, failover, restore) | ref/cloud.md |
| Develop locally now, ship to production later | Start with ref/local.md; it points to ref/cloud.md when it's time to go to prod |
If it's genuinely ambiguous (e.g. "set up Postgres for my app"), default to local for development tasks and ask before creating anything in the cloud — cloud services cost money.
Prerequisites (both workflows)
Check that clickhousectl is installed:
which clickhousectl
If not found, install it:
curl -fsSL https://clickhouse.com/cli | sh
This installs to ~/.local/bin/clickhousectl (with a chctl alias). If the command is still not found, suggest export PATH="$HOME/.local/bin:$PATH" or a new terminal.
All commands accept --json for machine-readable output. Exit codes follow gh conventions: 0 success, 1 error, 2 cancelled, 4 auth required.
