Never mind--answered my own question.
You can dump from a temporary table, which provides Hanan another way to
dump a subset of data.
Use CREATE TEMPORARY TABLE as select ....

I don't believe there is an option in pg_dump that current handles that.
It is the whole table / object or nothing at all. Depending on the
volume of transactions and frequency that you need to dump the data will
determine which solution works best for you.
Heavy volume and/or dumps multiple times per hour: Replication would
probably be the best solution-perhaps Slony.
Occasionaly or small volume: A Perl script / cron job that executes a
SELECT * FROM x WHERE date > $passed parameter when calling the script.
One time: Use pgadminIII or psql to execute a SELECT query and direct
the results into a file.
