Well, actually he *is* using such a zone:

regression=# select * from pg_timezone_names  where name = 'CET';
 name | abbrev | utc_offset | is_dst 
------+--------+------------+--------
 CET  | CEST   | 02:00:00   | t
(1 row)

But

regression=# select * from pg_timezone_abbrevs  where abbrev = 'CET';
 abbrev | utc_offset | is_dst 
--------+------------+--------
 CET    | 01:00:00   | f
(1 row)

The problem is that one of these two statements is using the abbrev
meaning and the other is using the timezone meaning.

We don't have much control over the zone definition, so I'm thinking
maybe the abbrev should be removed from the tznames lists.  But that
seems a bit sucky too.  Does anyone have any idea if the zic folk would
be responsive to a complaint that defining a timezone with the same
name as an abbreviation is a bad idea?
