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);:
I think the problem is the above- ^^^^^^^^^^^^^^^
username=db_link should be user=db_link
The accepted keywords are here:
http://www.postgresql.org/docs/9.3/static/libpq-connect.html#LIBPQ-CONNSTRING
31.1.2. Parameter Key Words
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?
Regards
