Docbase could not connect to the database error in documentum content server installation - postgresql

Question

While I am installing Documentum content server on AWS EKS, I am receiving this Error.
Postgress DB is installed on EC2 VM.

You are now connected to database "dm_postgres_docbase" as user "postgres".

I don't understand how to make it working.
Even I am facing issues with Postgres RDS Instant i.e.
GRANT "postgres" TO ""
The log is getting generated on PostgreSQL ec2 instance

I am using PostgreSQL superuser login and is working fine with cli.
updated the value in heml chart i.e values.yaml for documentum : content-server.

Every time you try to re-run the install you should completely delete everything. It looks like Postgres has the tablespace already created and that's why the test is failing
