I've set up tables with 500 million or more rows just as I would with
any other table. There is no table partitioning per se in postgres, but
you can always modify your application to use separate tables (which I
have also done for some large ones).
As for performance, that is soooo application dependent that you really
probably want to hire a consultant to help you out if you don't have time
to spend studying it yourself.
At the very least, for anything big like this, you'd want to spend
a week or two playing around with your database and application on
postgres before you even think about whether you want to convert or not.
