Hi, Tom and Magnus,

Thanks for your information for this issue.

Can this be a solution for this issue to add an option CREATE_NEW_PROCESS_GROUP to CreateProcess() function into pg_ctl.exe to start postgres.exe process?

That definitely sounds like it should be worth a try.

Unfortunately, we also met this issue, with poor reproducibility, when we running the postmaster as Windows Service.

Maybe this is another story than launching it manually by pg_ctl.exe.

I will update you if I get any new information.

That sounds very strange. I'm not saying you're not running into an issue there, but my guess would be you're actually running into a different problem (which may have similar symptoms).
