are you on release 0.4.0 ? attached is the full script i was using, i
moved the tables around so that I could use drop_all()/create_all().
Additionally, I just remembered that there are often dictionary-
ordering related issues which will occur on linux but not OSX (which
is my normal platform). So I'll try on linux later today...or if
anyone else wants to run the attached script with PG, SA0.4 and a
linux machine that would be helpful.
