- Adds CREATE OR REPLACE VIEW support for regular views with auto-detection (PostgreSQL/MySQL) to enable atomic updates.
- Implements automatic index management for materialized views, detecting and migrating all index types alongside view definitions. Both features include user override capabilities.
Add comprehensive tests for materialized view index detection
- Add helper functions to tests/asserts_utils.py for index verification
- get_index_names(): Get all index names for a table
- index_exists(): Check if specific index exists
- get_index_definition(): Get full index definition from database
- Add MaterializedViewWithMultipleIndexesTemplate test model
- Supports testing multiple index types and configurations
- Create tests/test_materialized_view_indexes.py with 8 test cases:
- Test basic index detection with get_migration_indexes()
- Test index recreation when view definition changes
- Test multiple indexes with different properties (unique, partial, multi-column)
- Test forward and backward migration with indexes
- Test views without indexes don't generate index operations
- Test index definition formatting (USING btree)
- Test no duplicate operations on subsequent makeviewmigrations
- Enable previously skipped test for materialized views with indexes
- Remove @pytest.mark.skip from test_materialized_db_view_based_on_raw_sql_with_indexes
