Previously, GetViewBaseRelids() rejected any query with more than one base table, so materialized views defined with JOINs were never registered in gp_matview_aux/gp_matview_tables. This meant no status tracking and no staleness propagation for join matviews. Add a recursive helper extract_base_relids_from_jointree() that walks RangeTblRef, JoinExpr, and FromExpr nodes to collect all base relation OIDs. This is the only C function changed -- the existing downstream infrastructure (InsertMatviewTablesEntries, SetRelativeMatviewAuxStatus, MaintainMaterializedViewStatus, reference counting) already supports N base tables per matview. This is a first step toward AQUMV support for join queries. Users can also inspect a join matview's freshness status manually via gp_matview_aux. Key behaviors: - Self-joins (t1 JOIN t1) are deduplicated to one catalog entry - All join types supported: INNER, LEFT, RIGHT, FULL, implicit cross - Subquery/function RTEs in FROM are still rejected - Partitioned tables in joins propagate DML status correctly - Status escalation across multiple base tables works (i→e on delete) - Transaction rollback correctly reverts status changes Includes regression tests for: two/three-table joins, implicit joins, self-joins, all outer join types, mixed join types, join with GROUP BY, shared base tables across multiple MVs, multi-DML transactions, transaction rollback, cross joins, partitioned tables in joins, VACUUM FULL, TRUNCATE, WITH NO DATA, and DROP CASCADE. <!-- Thank you for your contribution to Apache Cloudberry (Incubating)! --> Fixes #ISSUE_Number ### What does this PR do? <!-- Brief overview of the changes, including any major features or fixes --> ### Type of Change - [ ] Bug fix (non-breaking change) - [ ] New feature (non-breaking change) - [ ] Breaking change (fix or feature with breaking changes) - [ ] Documentation update ### Breaking Changes <!-- Remove if not applicable.
