pgAdmin4 connecting to Greenplum Community Edition v6.4 shows error

Hi, Team,

Recently I tried to connect pgAdmin4 4.20 (running under Windows 10
desktop) to a Greenplum Community Edition Cluster (obained from
https://github.com/greenplum-db/gpdb/releases) but I get some error
messages in the database log.
For example:

At the same time, I get errors in dashboard page.

Since I find that pgAdmin4 shows some Greenplum-specific features,
I guess pgAdmin4 supports Greenplum database, which is a Postgres-derived
open-source project.

Below is the output of SELECT version();
------------------------------
postgres=# select version();

version
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
PostgreSQL 9.4.24 (Greenplum Database 6.4.0 build

------------------------------

Is it possible to improve pgAdmin4 to fix this issue?

Or, Should I just turn off dashboard feature?

Best Regard.
