hmm all that code makes me wonder a bit about a more general issue - is
the "fallback to GMT if we fail to actually make sense of the right
imezone to use" actually a good idea?
In the case of the person I helped diagnosing the issue pg was bundled
into some commercial app and the only reason the user immediately
noticed that something was "wrong" was because the app used something
like "select now()" to display the current time in the GUI.
I would consider the failure to make sense of the registry on windows or failure to figure timezone information out a
moreserious issue than a
mere "WARNING" because depending on how you look at the issue it might
actually cause silent data corruption.
