Issue backing up the Ranger KMS DB?

[#1]

Hi,

Can you provide the procedure for backing up ranger kms? I've backed up the ranger and ranger audit databases using the postgres dump command (pg_dump), but I'm running into an issue when I try the same procedure for the rangerkms database. I tried the following command and got the error shown below. To access the ranger kms I have to login using the keyadmin user. I was thinking that this is my issue, that I'm trying to create a backup of this database using the wrong user? Any thoughts are suggestions are appreciated as I haven't been able to find any support articles on this. Thanks in advance...

pg_dump -U rangeradmin rangerkms > rangerkms.sql

Password:

pg_dump: [archiver (db)] query failed: ERROR: permission denied for relation ranger_masterkey

pg_dump: [archiver (db)] query was: LOCK TABLE public.ranger_masterkey IN ACCESS SHARE MODE
