You can get many varieties of SSH for windows. Probably the easiest
to install is the one that comes with Cygwin.

I'm the author of DBI-Link, and I am *always* eager to hear
suggestions for how to improve it. Concrete suggestions that come
with resources like testers, test environments, test plans, and so

I'm working on this. The next performance improvement relies on pg
8.1 features of PL/Perl. Further improvements...well, you're right.

and push them to an opaque place, in my case, a set-returning
function, at run time.
