You sure? FWIW, I get the same thing on my Linux dev box:

hassan@ceylon:/tmp> tar tvfz postgresql-8.4.1.tar.gz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error exit delayed from previous errors

Not sure what readline has to do with the original question
, but

> hassan@ceylon:/tmp> tar tvfz postgresql-8.4.1.tar.gz

for that file at least, the md5 checksum is not what's listed:

MD5 (postgresql-8.4.1.tar.gz) = efb12995609aaba2ee5d43b03be161c6
(pulled from a US mirror)

hassan@ceylon:/tmp> md5sum postgresql-8.4.1.tar.gz
3546300baee928ce0f254aafdfa6a1dc  postgresql-8.4.1.tar.gz
hassan@ceylon:/tmp>

Seems like something's not right there :-)

Just that I was able to use my tar on a 'normal'  tared up set of
files, i.e. maybe something is odd about the postgresql-8.4.1.tar.gz

I'd say no "maybe" about it, if the checksum doesn't match -- after
all, that's why one's provided: to confirm the file is uncorrupted  :-)

So, which mirror has got the bad copy?  I tried pulling it down
yesterday, and got a good copy, but that only proves there's at
least one US mirror with a good copy ...

There is no such location... if you look closer you'll see what you
have is a 404 Not Found response, which Safari has helpfully wrapped
up into a .gz file :-(

Run "file postgresql-8.4.1.tar.gz" and it will likely say it is an HTML file.

$ curl -O http://www.postgresql.org/ftp/source/v8.4.1/postgresql-8.4.1.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   239  100   239    0     0    306      0 --:--:-- --:--:-- --:--:--     0
$ file postgresql-8.4.1.tar.gz
postgresql-8.4.1.tar.gz: HTML document text

If you use curl's -f option, it makes more sense, though:

$ curl -f -O http://www.postgresql.org/ftp/source/v8.4.1/postgresql-8.4.1.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (22) The requested URL returned error: 404
