You are asking the right questions of the wrong group.  Postgresql is a
database. Or more completely and Object-Relational Database Management
System.  Postgresql keeps track of data.  Your "problems" or tasks are
more appropriately in the area of application.  So if you want it to
postgresql can store your data that your salesman collects, that gets
e-mailed to customers, and that comes in via the web.  But in and of
itself it won't collect, send, or provide a web interface.

Good luck.


Well, anyway, I was reading this James Bond book, and right away I
realized that like most books, it had too many words.  The plot was the
same one that all James Bond books have: An evil person tries to blow
up the world, but James Bond kills him and his henchmen and makes love
to several attractive women.  There, that's it: 24 words.  But the guy
who wrote the book took *thousands* of words to say it.
	Or consider "The Brothers Karamazov", by the famous Russian
alcoholic Fyodor Dostoyevsky.  It's about these two brothers who kill
their father. Or maybe only one of them kills the father.  It's
impossible to tell because what they mostly do is talk for nearly a
thousand pages.  If all Russians talk as much as the Karamazovs did, I
don't see how they found time to become a major world power.
	I'm told that Dostoyevsky wrote "The Brothers Karamazov" to
raise the question of whether there is a God.  So why didn't he just
come right out and say: "Is there a God? It sure beats the heck out of
me." Other famous works could easily have been summarized in a few

* "Moby Dick" -- Don't mess around with large whales because they
symbolize nature and will kill you.
* "A Tale of Two Cities" -- French people are crazy.
