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.

**Table 1** GS_MATVIEW_DEPENDENCY columns
Name	Type	Description
oid	oid	Row identifier (hidden attribute, which must be specified)
matviewid	oid	OID of a materialized view
relid	oid	OID of a base table of a materialized view
mlogid	oid	OID of a Mlog table which is the log table of a materialized view. Each Mlog table corresponds to one base table.
mxmin	int4	Reserved column
