Thanks to the team's work on TOAST, performance is about equal. The
real question for you to answer is what better suits your data? If
you are using the database for version control, or to serve web pages,
then I would say definitely in the table. However, if this is a
document tracking database just designed to help you find papers, then
I would say use linked files.

If you store the data in the database, you may have to pay close
attention to your disk allocation. If this database sees heavy use,
you may even need to move just that table to a seperate disk to
prevent disk-access slowdowns. Of course, if you are using RAID-5,
this is not an issue.
