IMO this is one of many reasons why Windows isn't a great choice of
platform for production use of Postgres ;-).
I hear that Microsoft is going to start embedding some flavor of
Linux in Windows, which presumably would extend to having a copy of
/usr/share/zoneinfo somewhere. It'll be interesting to see how that
works and whether they'll maintain it well enough that it'd be a
plausible tzdata reference.
