It seems right now SYSTEMQUOTE is used before popen both for
Windows and non-Windows, ex. adjust_data_dir() in pg_ctl.c

Won't defining variant of popen just for Windows to add SYSTEMQUOTE
effect such (where currently it is used for both win and non-winows)
usage? Also, I think we might want to remove use of SYSTEMQUOTE
before popen calls where ever it is currently used to avoid usage of the
same two times.
