Re: initdb error: create shared memory segment: Function

I don't have my windows pc handy but I seem to remember something in the
readme about how postgres may crash if you try to use initdb with a
different locale other than C under cygwin.

Try initdb without specifying the locale.  When you create the
individual databases you can specify the locale as Latin1 or something
else.
