User Account Requirements

For DumpBasedBackupSet, verify that the PostgreSQL agent has a user account with sufficient privileges to perform the following:

• Perform backup and restore operations

• Access the PostgreSQL database objects as part of the subclient content

  The following table illustrates the necessary privileges the user account should have to perform backup and restore operations:

  Initially, the user account credentials are provided during the instance configuration after the installation of the agent. You can change the user account at the instance level.
