Expect the uncompressed database to take up 40 or so gigabytes.

If you want to do that, I would probably write a meta-script that runs
through the TIGER/Line files and discards/rebuilds the database after
each county. If you actually want the PostGIS database but still want
to extract Shapefiles, you can build county polygons from the
CompleteChain rows with the side1 column set, and then do some fancy
polygon queries to extract data by county, I expect.
