I brought this up a while ago, but I didn't get any responses, I assume
due to everyone being too busy with 8.3
I think that it would be great if the pg_timezone_names and
pg_timezone_abbrevs included a boolean field indicating if that item is
in the Olsen DB or if it is a system alias or other added item. This
would make it far easier to integrate the data in the view with external
data sources that also use the Olsen DB.
It may also be beneficial to add the ISO 3166 column into that view, the
data is in zone.tab and I can't see a reason to not include it.
