Hmm... I'd better get to Amazon, thanks.

Why store the whole document in PostgreSQL? Why not leave it on the
file system where you can have at it with xsltproc or xalan?
Incidently, I am building a document management system in PostgreSQL
that manages XML documents. This subject is very interesting to me.
I've found that mapping XML data to an RDBMS is difficult and
kludgy. It was a real breakthough for me when I realized that not
every document had to be ER modeled.
