In one of our servers, we installed new pgAdmin 4 and PostgreSQL 9.6 server. We are also working in Greenplum Database which uses PostgreSQL 8.2 as core an RDBMS.
We tried to connect our Greenplum server using pgAdmin 4, and got the below error:
Unrecognized configuration parameter “bytea_output”
Why? – Because, PostgreSQL 9.0 and earlier versions are not supported by pgAdmin 4. So for older PostgreSQL versions, we have to use pgAdmin 3 still.
