pg_ctl spawns visible CMD window on Windows 11 (expected hidden)

[mushonnip]

Describe the bug

When using postgresql-embedded in a Tauri application on Windows 11, launching the embedded PostgreSQL causes a visible CMD pg_ctl.exe window to flash.

This breaks the clean user experience expected from a GUI app in production.

On Linux, the behavior is correct: PostgreSQL starts silently in the background.

Expected behavior

PostgreSQL should start silently, with no visible command prompt or just a tray icon.

Environment

OS: Windows 11
postgresql-embedded version: 0.18.5
PostgreSQL version: 16.9
Rust: 1.87.0
Tauri: 2.5.1

@mushonnip thank you for reporting the issue. I believe #197 will prevent the window from being created; however, I do not currently have the ability to reproduce the problem to test the fix. The change has been released in 0.18.7. If you could verify this is fixed in your environment and follow up here with the results I would appreciate it.

@brianheineman Thanks for the quick update and the fix!

I've tested with version 0.18.7, and I can confirm that the issue is resolved. No more CMD window appears when starting the app. Everything runs silently as expected.

This fix really helped clean up the user experience in production, so I truly appreciate the support. Thanks again! 🙏
