dblink password required

Hi,

I’m trying to use dblink to connect from database1 to database2 on the same machine. The Postgres version is 9.3.5.

Firstly, I’ve created a user to use with the connection, while logged in as the postgres superuser to database2:

> create user db_link with password ‘mypassword’;
> grant select on appuser to db_link;

Secondly, the following has been added to pg_hba.conf and a restart done.

# dblink between database1 and database2
local database2 db_link md5
host database2 db_link 127.0.0.1/32 md5
host database2 db_link ::1/128 md5

Connecting with PSQL prompts for a password as expected:

> psql -U db_link -d database2
Password for user db_link:
psql (9.3.5)
Type "help" for help.

Then, as a normal user logged into database1, I tried

> select * from dblink(‘dbname=database2 username=db_link password=mypassword','select username, email from appuser') as t1(username text, email text);

However this returns

ERROR: password is required
DETAIL: Non-superusers must provide a password in the connection string.

This is my first time trying dblink so there’s probably something simple I’m missing, but I thought I had provided a password. Any ideas?
