pg_dump?

PostgreSQL begginer. Whats the best way of exporting(dumping) a database/table/view/query to a file? 
I am using PostgreSQL v 8.2.  I am starting postgres server with 
C:\WINDOWS\system32\net.exe  start pgsql-8.2, (start service)
C:\postgresql-8.2.3-1\bin\psql.exe  -h localhost -p 5432 postgres "Richard" 
(psql to 'postgres')
both of which are run from shortcuts in the start menu. 
my cli starts with "postgres #", then "databasename #" after connecting using \c.

Richard.
