I use PostgreSQL

  I run PostgreSQL on my GNU/Linux system which is a (very heavily)
modified version of a Slackware 7 distribution, running on an
AMD-K6/225MHz. I used egcs-1.1.2, _with -O9 optimization_.
  Not every regression test succeeded, and I'm including the regression
output file.

  Thanks for your great work.
