I am not sure what kind of data model would require 255 columns, but

You can create multiple bound table(sort of like a vertically
partitioned view). In each bound table in access only include the
primary key and a subset of the columns. Of Course this will probably
complicate your application design.

I don't believe that you can bind oracle table to postgresql. There
is a module dbi-link that is similar to what you want to do. This
page might give you some ideas about what is available:
