Their SCM tip successfully builds our code with --enable-dtrace.
I haven't gotten any further with it than to try the sample script
linked on the page above, but that seemed to work (on a Fedora 10
x86_64 box).
The current 0.9 release does *not* work on our CVS tip (dtrace fails
on more-than-6-argument probes, and there are some other issues),
but you can pull from their git repository:
install elfutils-devel
git clone git://sources.redhat.com/git/systemtap.git
configure --prefix=SOMEWHERE
make all
sudo make install
Then build PG with
PATH=SOMEWHERE/bin:$PATH
configure --with-includes=SOMEWHERE/include --enable-dtrace
