That will not work --- the 8K limitation is on the total size of a tuple
(record), not on the size of individual fields in it. You could make a
table with fields "docid", "partno", "content" and then insert the data
of a document into multiple records with the same "docid" and varying
"partno". It's a pain though. I hope to see the 8K/tuple limitation go
away in the next release or two.

The total size of the table is not a problem --- you'll run out of disk
space first.

Yes, you could store the text in external files and just refer to those
files in the DB entries. Not a real satisfactory solution, but it might
do as a workaround. A variant on this is to keep the text in "large
objects" within the SQL DB, but those are hard to use; worse, they're
not real efficient if you have a lot of 'em.
