Putting restrictions on pg_dump?

Is there a way to put a limit on pg_dump, so that it doesn't dump ALL data,
but that matching a particular query?

Something like:

pg_dump -da --attribute-inserts -t "customers" \
--matching-query="select * from customers where id=11";

I'd like to selectively dump information from a query, but using the output
format from pg_dump so that it can be used to create a (partial) database.

Can this sort of thing be done?
