Обсуждение: Facing authentication error on postgres 9.2 -> dblink functions

Hello Everyone,

I am using postgres 9.2 and when executing function dblink facing a fatal error while trying to execute dblink_connect as follows:

    SELECT * FROM dblink_connect('host=127.0.0.1 port=5432 dbname=postgres password=test')

    ERROR: could not establish connection DETAIL: FATAL: password authentication failed for user "NETWORK SERVICE"

What this error is related to? Do I need to modify pg_hba.conf file by any chance?

Thanks..

You should specify a user=username option in the connection string,
otherwise that defaults to your operating system user name.

Do NOT send questions to multiple lists. That is a waste of everybody's
time. So do NOT follow up this email. This question belongs on
pgsql-general. If you have further questions pleease ask there.

The short answer is that you need to provide the user name in your
connect string.
