new graphics file?

There is a new Postscript graphics file in doc/src/graphics/catalogs.ps.
I assume that the comment in the log:

revision 1.1
date: 1998/08/11 02:32:00;  author: momjian;  state: Exp;
New findoidjoins examines oid columns to find join relationships.

may mean that something in that is different than for the original file
catalogs.gif. Is the source available in something other than Postscript
or gif? I had checked in .gif files to allow building the html easily,
and checked in the .ag (Applix graphics) files as sources I had
converted from the original gif files, expecting to move to another
format at some point. Hannu and I had concluded (last spring?) that CGM
format might be the most portable, but we didn't actually commit to
changing to that for the sources.

Anyway, let me know what's available; I'm past due on starting the
hardcopy docs integration...
