Is there any reason that the zone.tab information is not included in the
pg_timezone_names system view? ISTM that there is really no reason not
to, as that view is really populated using that file anyway. There is a
1:1 mapping (assuming the aliases are mapped to the zone.tab entries
they are
Sorry to reply, but there should also be a field in the system view
is_alias so that devs are able to tell which zone names are in the
zone.tab file and which are not. That way a perfect 1:1 mapping between
zone.tab and app can be made. If this were done then it'd make things
like using CLDR
