Re: xml middleware

I was even thinking more along the lines of a java program that acts as an
interface where it receives a query from the user, sends it to postgreql via
jdbc, receives the result set, translates it into XML and returns it to the
user.

Performance would be the isue, but something like that would be best suited
for internet applications and the performance is not as big of an issue.
Plus, if you plan on using XML, you are expecting to take performance hits
anyway.
