Re: proposal - psql - use pager for \watch command

Hi

Here is a little bit updated patch - detection of end of any child process
cannot be used on WIN32. I am not an expert on this platform, but from what
I read about it, there is no easy solution. The problem is in _popen
function. We lost the handle of the created process, and it is not possible
to find it. Writing a new implementation of _popen function looks like a
big overkill to me. We can disable this functionality there completely (on
win32) or we can accept the waiting time after pager has ended until we
detect pipe error. I hope so this is acceptable, in this moment, because a)
there are not pspg for windows (and there was only few requests for porting
there in last 4 years), b) usage of psql on mswin platform is not too wide,
c) in near future, there will be an possibility to use Unix psql on this
platform.
