Foreign PostgreSQL server

Hi!

Sorry if this was already asked.

My platform: Win7, PostgreSQL 9.1 64bit installed using EnterpriseDB
package.

I’m trying to setup a bunch of foreign PostgreSQL servers, but whenever I
execute the script below, I get errors:

----------------------------------------------------------------------------
--
drop foreign data wrapper postgresql_fdw cascade;

create extension dblink;

CREATE FOREIGN DATA WRAPPER postgresql_fdw
VALIDATOR postgresql_fdw_validator
HANDLER postgresql_fdw_handler;

CREATE SERVER simfrete02 FOREIGN DATA WRAPPER pgsql OPTIONS (host
'127.0.0.1', dbname 'simfrete', port '5432');
----------------------------------------------------------------------------
---
And the errors are:
ERROR: function postgresql_fdw_handler() does not exists

********** Error **********

ERROR: function postgresql_fdw_handler() does not exists
SQL state: 42883

Can you point what I'm doing wrong?

Thanks & Regards,
