You can usually use pg_dump to accomplish such tasks.  It's not something
likely to be implemented any time soon now that schemas have been
implemented.  If you have no great reason to have two seperate databases
versus two schemas, you may want to investigate using schemas in the
future.

For now, you can do something like:

pg_dump -d db1 -t table1 |psql db2

then psql and do

insert into table2 (select * from table1);
