Re: a few simple questions

1.  A FAQ can be found at http://www.postgresql.org/docs/faq-english.html,
the a book is at http://www.postgresql.org/docs/awbook.html, searchable
archives of lists at http://www.postgresql.org/gen-info.html and lots of
documentation accessable via postgresql.org under the 'user's lounge'.
2.  My understanding is that permissions are based on objects within the
database, not the DB itself...  Example:  if user_a creates a table called
table_a in a DB, upon connection to the DB, user_b should not be able to
perform DB functions (such as select, update, delete, etc.) on table_a
unless specifically granted permissions to do so by user_a (see GRANT in the
PostgreSQL User Docs).  On another note, by adding entries in pg_hba.conf,
you can set up PostgreSQL to allow/reject connections to specific DBs from
specific ips (or blocks of ips) or usernames, while rejecting all other
connections.
3. Try ALTER USER username WITH PASSWORD 'password', where username is the
name of the user whose password is to be changed, and password is the new
password.  (From the PostgreSQL User Docs:) Only a database superuser can
change privileges and password expiration with this command. Ordinary users
can only change their own password
4.  What exactly do you need help with?
