A %triggerin scriptlet could update the symlinks with every tzdata

I think rpm will just remove the files in /usr/share/zoneinfo as the
%post script will be executed before the files of the old package are
removed. A %posttrans scriptlet could be better.
Making the symlink as /usr/share/pgsql/zoneinfo and changing all paths
in postgresql accordingly is not an option?
