Thanks Richard. I guess I got confused by the Stata Manual:
You can also set it up as a regression problem, in which case you could do it in Stata 9:

webuse nhanes2f
xi: svy: reg health i.race
test _Irace_2 _Irace_3, mtest(b)

As I think about it though, I am not sure if this is giving you exactly what you want. It is giving you comparison of 1 versus 2 and 1 versus 3, but not 2 versus 3. If you were using the oneway command with non-svy data, you would get all three contrasts. So, maybe this doesn't solve your problem after all?

Of course, doing a bonferroni adjust by hand isn't all that hard and could perhaps be automated. Maybe set up a loop to do a bunch of test commands.
