Research direction
Start by reading org.apache.linkis.metadata.query.service.postgres.SqlConnection, which the issue identifies as lacking schema retrieval. Trace how Exchangis requests metadata after a database is selected, then verify that PostgreSQL and Greenplum connections expose their schemas. Done means the schema is displayed for the reported environment.
