Huh. I thought PostmasterHandle should be signalled by the kernel,
not by any code

Greetings,
When the postmaster exits unexpectedly on Windows (crash, kill, debugger
abort), backend processes continue running. Windows lacks any equivalent
to Unix's getppid() orphan detection. These orphaned backends hold locks
and shared memory, preventing clean restart. This leads to a delay
