hmm ... I get something reasonable here:
regression=# set timezone = '-6';
SET
regression=# show timezone;
TimeZone
-----------
-06:00:00
(1 row)
Could you poke into this more and find out why it goes wrong on your
platform?

That one works for me too...

This is not totally surprising, seeing that they go through completely
different code paths. I believe "set time zone" accepts whatever the
underlying OS's tzset() routine will take, whereas "at time zone"
only accepts timezone names listed in datetime.c's builtin table.
The difference could and someday should be eliminated, but it will
take rewriting a lot of OS-level timezone support for ourselves :-(
