All I can find with a quick Google search for "SKYLINE postgresql" is
references to someone's masters thesis, plus a bit of mailing list
discussion.

There's no indication it was ever proposed and discussed as a serious
patch to the core of PostgreSQL, let alone applied. Have a look at this
thead, including follow-ups.

The masters thesis page does contain a patch against PostgreSQL 8.3: http://skyline.dbai.tuwien.ac.at/
but this is something you have to apply to the source code, then compile
PostgreSQL into usable binaries. That's trivial on Linux, but I don't
recommend you try it on Windows, as compiling software on Windows is
much more complex.

They say they're porting the patch to 8.4devel, but I suspect that since
8.4 has been out for ages and 9.0 is almost released, they've probably
lost interest and dropped the work.
