Bug: postinstall script fails on Windows

[chrille0313]

Description

The pgflow package's postinstall script fails on Windows, preventing installation via npm install pgflow or npx pgflow@latest install.

Steps to reproduce

1. On Windows (PowerShell or cmd), run: npx pgflow@latest install
2. Or: npm install -g pgflow@latest

Expected behavior

Installation completes successfully.

Actual behavior

Installation fails with:

npm error command failed
npm error command C:\WINDOWS\system32\cmd.exe /d /s /c chmod +x dist/index.js || true
npm error 'chmod' is not recognized as an internal or external command,
npm error operable program or batch file.
npm error 'true' is not recognized as an internal or external command,
npm error operable program or batch file.

Root cause

The postinstall script runs chmod +x dist/index.js || true — Unix commands that don't exist on Windows.

Workaround

Install with scripts disabled, then run the CLI:

npm install pgflow@latest --ignore-scripts
npx pgflow install

Environment

• OS: Windows 10/11
• Node: v24.12.0 (also reproducible on other versions)
• npm: latest
