PostgreSQL Source multi hosts config on Dremio

Dears,

We need to query PostgreSQL in Dremio , we have more than one host like host1:8080,host2:8080,host3:8080.

The host port are same, but host is different, how to config it?

Best Regards

@Junwei Is this something like Oracle RAC, the Database (disks) are the same right? Is this more like HA? How do you pass info from say something like PgAdmin?
