the PG driver works out of the box. I've had no issues with the tcl library, but I am using 3.2.5. I can't think of any reason 4.x would have trouble, though.
So what we're saying here is that PG and tcl arent an issue but serving up utf-8 pages wont work.
That would definitely break our application.
Maybe recompile the ArsDigita contribution for UTF-8 support?
I have to find a way of stabilizing this server. Maybe I can get away with DaemonTools restarting AOLserver whenever it crashes which can be either once in 2 weeks or twice in one day.
