copying a db

[Daniele Migliau <Daniele(dot)Migliau(at)ingegneria(dot)studenti(dot)unige(dot)it>]

Hi to everyone,
   I'm new to postgresql and i have a question.
I'm working on a university experimental project that parses data from 
an on-line postgresql database (i.e. I access to the DB via web with 
PgAdminIII without problems).

In order to work when I won't have an internet connection, I decided to 
copy the entire on-line database (even a few tables are sufficient) on 
my local machine, where I have installed postgresql 8.0.

How can I do? Is there any function I can use? Please tell me in details 
as I'm totally new to postgresql.

Thanks in advice,

Daniele.
