Issue with deploying PostgreSQL in local setup

I have used following link as reference to deploy PostgreSQL in local instance:

 https://academy.creatio.com/docs/user/setup_and_administration/on-site_deployment/database_server/deploy_postgresql_database_windows

 As mentioned in the link, I have created 2 user roles- sysadmin and public user profile(to set up connection to the restored db). whenever I use public user login in connection config file, I get an error: "42501:permission denied for table SysSettings".

However sysadmin credentials seem to work.  Kindly help in resolving the issue.
