Hi,
I'm evaluating the knowage bi for OLAP use cases where i tried to create a metadata model using Redshift data by using postresql jdbc driver but below are the error which i'm geeting.
I also tried with MySQL and Postgresql datasource and its working fine. It seems there is some issue of comapctibilty b/w postgres and Redshift JDBC driver.
Can anyone please suggest is there any possible way to directly add Redshift Data Source Dialect/Redshift JDBC driver for data connections.

Also attched errro log below Error while getting structure of data source by id
org.postgresql.util.PSQLException: ERROR: type "e" does not exist
