GS_MATVIEW_DEPENDENCY

GS_MATVIEW_DEPENDENCY provides association information about each fast-refresh materialized view, base table, and Mlog table in the database. The Mlog table corresponding to the base table does not exist in the complete-refresh materialized view. Therefore, no record is written into the Mlog table.
