I agree. (Note that this is dev/test/uat, not prod/dev).
But it really depends on his usage patterns and such. If he's not
planning on doing any functions in C, and assuming that testing of
things like pgsql / jboss / apache will be done on another system
entirely, then it might well be easier to run everything from one
database server.
I think we need to know more about the planned usage to really say one
way or the other.
