Well, to store entire XML documents. So-called
'document-centric' XML. Things like articles, interviews, press
releases, photo essays, etc. And then be able to do X-Path (or
X-Path-like) queries on them.
I'm an absolute beginner on this issue. I was looking for a
solution to the implementation of a document publishing system
using Python & PostgreSQL, and this appears to be the right
direction.

The seemingly ceaseless stream of 'Working Draft' and 'Candidate
Recommendation' announcements from the W3C leaves me on the
verge of a hissy fit. Not to mentioned very confused.
Leaving aside what might come to be in the future, the reality
is that ways & means of dealing with XML right now in PostgreSQL
*are* needed and Gray's contrib/xml seems like a good start.
I imagine that a workaround is possible in PostgreSQL using the
idea mentioned in the articles cited above, of storing the XML
document in it's entirety in one table and using another table
as an 'index table'.
