Are there plans to add support for Greenplum 7? There were some catalog changes due to the underlying version of PostgreSQL and the existing Greenplum driver doesn't work properly.
No immediate plans, but we have added an improvement request for this.
From what we know Greenplum 7 is still in beta and may be released later this year.
As Greenplum 7 seem to be based on PostgreSQL 12 you can try connecting using the profile of PostgreSQL 8+.
