We will see below pg_dump is a regular IvorySQL client application (albeit a particularly clever one). This means that you can perform this backup procedure from any remote host that has access to the database. pg_dump must have read access to all tables that you want to back up, so in order to back up the entire database you almost always have to run it as a database superuser. (If you do not have sufficient privileges to back up the entire database, you can still back up portions of the database to which you do have access using options such as `-n *`schema`*` or `-t *`table`*`.) -​To specify which database server pg_dump should contact, use the command line options `-h *`host`*` and `-p *`port`*`. The default host is the local host or whatever your `HOST` environment variable specifies. Similarly, the default port is indicated by the `PORT` environment variable or, failing that, by the compiled-in default. (Conveniently, the server will normally have the same compiled-in default.) +​To specify which database server pg_dump should contact, use the command line options `-h *`host`*` and `-p *`port`*`.

Similarly, the default port is indicated by the `PGPORT` environment variable or, failing that, by the compiled-in default. (Conveniently, the server will normally have the same compiled-in default.) pg_dump will by default connect with the database user name that is equal to the current operating system user name. To override this, either specify the `-U` option or set the environment variable `PGUSER`. Remember that pg_dump connections are subject to the normal client authentication mechanisms 。
