The playbook

The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.

1. 01recondoes a PostgreSQL already exist? which version, service and folder
2. 02reconport 5432 free?
3. 03reconavailable package managers: winget (real path, often off PATH under SYSTEM), choco, and the account running commands
4. 04reconfree disk space on C: (≥ 2 GB recommended)
5. 05actGenerate the superuser passwordverify
6. 06actInstall PostgreSQL ${version}verify
7. 07actCheck the local connectionverify
8. 08actCheck network exposureverify

What it verifies

Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

1. 01verifyGenerate the superuser passwordVerified byTest-Path "$env:ProgramData\Servor\secrets\postgresql-${version}-postgres.txt"
2. 02verifyInstall PostgreSQL ${version}Verified by(Get-Service "postgresql-x64-${version}").Status
3. 03verifyCheck the local connectionVerified by& "$env:ProgramFiles\PostgreSQL\${version}\bin\pg_isready.exe" -h 127.0.0.1 -p 5432

Guardrails

Non-negotiable instructions the run must respect, whatever it finds on the server.

What you choose before launching — the recipe fills in the rest.

SEC.05

How a recipe runs in Servor

Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.

Deploy on Servor button

Maintain PostgreSQL (Windows) or a project that needs it? Put this button in your README or on your site: one click and your users install it on their own server.
