I can confirm this failure.

(in my case at least) pg_ctl is not seeing the full version string of the
postmaster in find_other_exec. This is due to the single call to ReadFile in
pipe_read_line, which is not returning the entire version string (losing all
characters beyond the last decimal point in the version string). A
subsequent call to ReadFile picks up the remainder of the string. I don't
see that we can rely on a single call returning the entire version string.

If someone can run with this, I've attached initial looping changes for
pipe_read_line. However I'm not sure of the correct terminating condition
(gets into a call to ReadFile that never returns; the WaitForSingleObject
appears insufficient as a precondition for ReadFile) and just don't have
time to complete it right now.

Cheers,
Claudio
