Partly no, partly yes. My focus was on verifying the accuracy of
identifying the actual postmaster PID on Windows. The current patch
provides a detailed description of the events, primarily because I
lack a comprehensive understanding of both the behavior of Windows
APIs and the associated processes.  Given that context, the messages
essentially serve debugging purposes.

I agree with your suggestion.  Ultimately, if there's a possibility
for this to be committed, the message will be consolidated to "could
not start server".
