Haven't tried compiling it yet. But for start, there is //-comments,
which I don't think will pass a C compiler. Again, haven't specifically
tested.

Also, if we are going with an outside "service wrapper", consider
putting the install and uninstall functions into this one as parameters
"-install" etc. One less binary to worry about.

I don't have your code around right now, so I don't remember if you had
already handled the "multiple instances on the same machine" issue. If
not, that would also be a nice feature :-)

The rest of the backend is BSD, so that would be most suitable.

Oh yes, but to catch the data, you need to get it from both the main
postmaster and from subprocesses.

'fraid I don't know much more about this - needs further research.
