Done that. Also, I needed to replace "gmake" with "make", since I'm on
linux...
Anyway. It's been running for about 12 hours now, and I have *nothing*
in the output file. That tells me that the script doesn't appear to be
working - correct? It should output *something* there, right? (It's
obviously running, because I've got about 400,000 lines in nohup.out..)
Argh. So here I am looking at it now for details, and it seems the
script should be run from src/test/regress, and I ran it from the root
directory.. Oops. Also, I needed to place psql in the path - it failed
to find it, but hid the error message.
Just a hint if someone else is running it ;-)
