     I disagree. When I read back the value the original timezone is lost. So
     it clearly DOESN'T store the timestamp WITH the timezone.


I never said it stored the timezone.  I said that it has a timezone.

The raison d’être of a database is to store data. If some data isn't
stored, the database doesn't have it, in my opinion.


But if you use timestamptz it does have it. The data(timestamp) is stored with time zone UTC. From there you can reconstruct the timestamp at any time zone you want, given the clients needs. I'm not sure why where it started is important when people care how it is presented to them on retrieval.
