Error: for dblink view

Objective :

1. Create new user (Ex. piam_card ) in postgres database

2. Create view (Ex. attendance ) using dblink functionality. The view will be created in Database 2 & view will have the inner join with database 1 tables

3. The newly created user (piam_Card) must have readonly permission to created view (attendance)

Please provide the steps to achieve above functionality.
