I agree.  While what timestamptz implements is a very useful data
type, I think it was a very unfortunate decision to implement that
for the standard type name, instead of something more consistent
with the spec.  It seems very unlikely to change, though, because
so much existing production code would break.  :-(

Understandably, people do tend to expect that saving something into 
a column defined as TIMESTAMP WITH TIME ZONE will save a time zone 
with the timestamp, and in PostgreSQL it does not.
