I have a few comments about this patch.

On HEAD and even after this patch, we still have the following:
SKIP:                                                                                                                                                                      {                                                                                                                                                                              skip "cancel test requires a Unix shell", 2 if $windows_os;

Could the SKIP be removed for $windows_os?  If not, this had better be
documented because the reason for the skip becomes incorrect.

The comment at the top of the SKIP block still states the following:
# There is, as of this writing, no documented way to get the PID of
# the process from IPC::Run.  As a workaround, we have psql print its
# own PID (which is the parent of the shell launched by psql) to a
# file.

This is also incorrect.
