I read all of the posts on Friday and was tempted to respond, but due to
mixed feelings I held off to mull over the issues during the weekend.
Unfortunately, I'm still not sure which solution is better:

    1. wrapping postmaster with cygrunsrv
    2. direct conversion of postmaster to a true NT service

Would you be willing to pose this question to pgsql-cygwin@postgresql.org
and possibly pgsql-ports@postgresql.org, to see if anyone (especially
the core PostgreSQL development team) has a strong preference?


Now back to the cygrunsrv...

On one hand, I like the idea of wrapping UNIX daemons with something
like cygrunsrv to ease the porting to NT.  On the other hand, there is
a certain appeal (at least to me) to have the UNIX daemon run as a true
NT service without a wrapper.  However, this has caused code duplication
in at least the following:

    postmaster (assuming Fred's first approach)

I was wondering whether or not it was worth it to structure cygrunsrv as
a library and a "main."  In this way, the porter could choose between the
simple (and quick) wrapping approach or linking with the library approach
to get a true NT service.  The former approach would probably handle most
of the cases while the latter would only be needed for daemons with special
requirements.  In either case, code duplication would be minimized.
