If the tables could be in the same database but in different schemas,
you should be able to arrange a view in schema2 (called "table2") with
rules that operate on table1 in schema1. See the manual for a discuss of
rules and views.
If you really want these tables in separate *databases* (same machine or
not), then you probably want dblink, a stiff drink, and a long-hard
think about the prudence of such a design.
