Thanks Rudic, that is nearly to what I am seeking for. Some pending are like,
1) I have approx 500 server for which space needs to be calculated.
2) And these server does not have setup ssh-keys as required.
3) To setup ssh-keys on these many servers is tough task.
4) Any other way to get these details without setup ssh-keys and giving password.
Please suggest.

CREATE
SERVER(7) PostgreSQL 9.2.7 Documentation CREATE SERVER(7)
NAME
CREATE_SERVER - define a new foreign server
SYNOPSIS
CREATE SERVER server_name [ TYPE 'server_type' ] [ VERSION 'server_version' ]
FOREIGN DATA WRAPPER fdw_name
[ OPTIONS ( option 'value' [, ... ] ) ]
DESCRIPTION
CREATE SERVER defines a new foreign server. The user who defines the server becomes its owner.
A foreign server typically encapsulates connection information that a foreign-data wrapper uses to access an external data resource.
Additional user-specific connection information may be specified by means of user mappings.
The server name must be unique within the database.
Creating a server requires USAGE privilege on the foreign-data wrapper being used.
PARAMETERS
server_name
The name of the foreign server to be created.
server_type
Optional server type.
server_version
Optional server version.
fdw_name
The name of the foreign-data wrapper that manages the server.
OPTIONS ( option 'value' [, ... ] )
This clause specifies the options for the server. The options typically define the connection details of the server, but the actual
names and values are dependent on the server's foreign-data wrapper.
NOTES
When using the dblink module (see dblink), the foreign server name can be used as an argument of the dblink_connect(3) function to indicate
the connection parameters. See also there for more examples. It is necessary to have the USAGE privilege on the foreign server to be able
to use it in this way.
EXAMPLES
Create a server foo that uses the built-in foreign-data wrapper default:
CREATE SERVER foo FOREIGN DATA WRAPPER "default";
Create a server myserver that uses the foreign-data wrapper pgsql:
CREATE SERVER myserver FOREIGN DATA WRAPPER pgsql OPTIONS (host 'foo', dbname 'foodb', port '5432');
COMPATIBILITY
CREATE SERVER conforms to ISO/IEC 9075-9 (SQL/MED).
