Обсуждение: Doubt about Databases

I'm starting to do a home page with a database using the PostgreSQL in
the server but I don't Know which database I should use. My questions
are :
  _ Using the PostgreSQL which are the databases that I can use?
  _ Can I use ODBC with PostgreSQL in a Unix Server?
  _ To do the database using PostgreSQL should I use the program that is
for download in this site or should I use other?

  Please, all things that you can say to me about this will be useful.

                                      Tank you very much,
                                                            Rodrigo.
