I didn't send patches since I wasn't sure if you were still working on it.

Something like "gzip -dc file.tar.gz | tar -xvf -" uncompress' it in place.
I'll play around with -C to move it around.

I don't really have a problem with gnu stuff, but the machine that I put
postgres on is a development machine here for other folks too.  Also used
for the src for our product line.  I can't just go drop in a new tar or
what not...

Not until I get some ideas on what would work better on more platforms...

Well, can't "uncompress" work with gzip'd files? I recall that it can, but that
may have been on a box (Dec Alpha?) with some upgraded "uncompress" capabilities.
If it can work, then we should do something like

  uncompress -c file.tar.gz | tar xf -

to get away from any non-generic utilities. Is zcat (== uncompress -c) standard
on all machines?

btw, for generating the docs tar files I used "--exclude='*.sgml'" options on
tar. Is that gnu-specific also?

Yep.  Any --X option is GNU, I think.

    gzip -cd will uncompress 'compressed' files, but compress can't
touch 'gzip'd files...
