table size/record limit

I am designing something that may be the size of yahoo, google, ebay, etc.

Just ONE many to many table could possibly have the following
characteristics:

    3,600,000,000 records
    each record is 9 fields of INT4/DATE

Other tables will have about 5 million records of about the same size.

There are lots of scenarios here to lessson this.

BUT, is postgres on linux, maybe necessarily a 64 bit system, cabable of
this? And there'd be 4-5 indexes on that table.
