"**schema_version** " does not exist" - Kubernetes deployment - dependency airbyte

Hi All,
I have recently tried to upgrade Airbyte application via helm chart to use external database - Postgresql. Initially, temporal db error message was displayed when i checked the pods failure log and so I manually created two databases, temporal and temporal_visibility. Now a new error is popping up "sql schema version compatibility check failed: unable to read DB schema version keyspace/database: temporal error: pq: relation “schema_version " does not exist”.
Please let me know what needs to be done to fix this issue.
Should i manually create schema_version table? what is the structure of the table? any other tables need to be created manually as a pre-requisite?
