Sample query

The following query returns an output row that indicates that the materialized view mv_over_foo uses the materialized view mv_foo in its definition as a dependency.

CREATE SCHEMA test_ivm_setup;
CREATE TABLE test_ivm_setup.foo(a INT);
CREATE MATERIALIZED VIEW test_ivm_setup.mv_foo AS SELECT * FROM test_ivm_setup.foo;
CREATE MATERIALIZED VIEW test_ivm_setup.mv_over_foo AS SELECT * FROM test_ivm_setup.mv_foo;

SELECT * FROM stv_mv_deps;
