Well, the plan choice *could* be platform-dependent, given that the
planner uses comparisons of floating-point cost estimates. But I agree
that's pretty unlikely. What seems to be more common is platform-
specific differences of behavior of qsort(). If you have any equal
keys in the row set being sorted, then the output ordering depends on
the whim of the qsort implementor...
