As far as I can see, it's an invented abbreviation propagated from tzdata, and there isn't much independent support for it. I've been trying to omit these inventions, as tzdata should record timekeeping not invent it.
I have gathered a few sources that mention WGT/WGST, but I honestly have no clue if these are based of off tzdata (which could very well be the case) or something else.: ... In any case I can't help feeling, that with all this "knowledge" out there, removing the WGT/WGST timezone abbreviations from tzdata seems wrong. These are the TZ abbreviations that we work with on a daily basis up here (I'm in Nuuk, Greenland) and suddenly they are unknown in our favorite timezone data.
FWIW, I tend to share the suspicion that these zone abbreviations have become normalized simply because they've been in widely-recognized reference data (to wit, tzdb) for years. Very few non-experts will know that they had no standing otherwise. The Postgres project has so far refrained from removing them from what we recognize in timestamp input, because we fear the backlash if we do. Most of our timestamp output formats represent timezone offsets numerically, so that the issue doesn't arise so much on that side, and it happens that our list of abbreviations recognized for input is separate from the tzdb data proper. regards, tom lane
