The following bug has been logged on the website:

Bug reference: 8901
Logged by: Alex
Email address: byteslayer7@gmail.com
PostgreSQL version: 9.3.2
Operating system: Windows 7
Description:

I posted a question on Stackoverflow regarding postgres_fdw. I was advised
to report it here and link to it:
http://stackoverflow.com/q/21193642/797021.

In short, the issue is that this psql input:
CREATE USER test_user SUPERUSER PASSWORD 'password';
SET ROLE test_user;
CREATE DATABASE import;
CREATE DATABASE export;
\c export test_user
CREATE SCHEMA export_schema;
CREATE TABLE export_schema.aa (
id serial PRIMARY KEY,
dat text
);
\c import test_user
CREATE EXTENSION postgres_fdw;
CREATE SERVER export_server
FOREIGN DATA WRAPPER postgres_fdw
OPTIONS (host 'localhost', dbname 'export', port '5432');
CREATE USER MAPPING FOR test_user
SERVER export_server
OPTIONS (user 'test_user', password 'password');
CREATE SCHEMA import_schema;
CREATE FOREIGN TABLE import_schema.aa(
id serial NOT NULL,
dat text
) SERVER export_server OPTIONS (table_name 'export_schema.aa');
SELECT * FROM import_schema.aa;

Which I expect to work, instead gives this error:

ERROR: relation "import_schema.export_schema.aa" does not exist
CONTEXT: Remote SQL command: SELECT id, dat FROM
import_schema."export_schema.aa"

This is documented in the postgres_fdw reference page, but I notice that
page has absolutely no examples. A concrete example or two might help
perhaps. Anybody feel like working up a patch?
