Description:

When running tests/types/test_range.py as the root user, multiple tests fail with InsufficientPrivilege errors related to the testrange function. The error explicitly states:gaussdb.errors.InsufficientPrivilege: Must be owner of function testrange.

ERROR tests/types/test_range.py::test_fetch_info_async[asyncio-testrange-text] - gaussdb.errors.InsufficientPrivilege: Must be owner of function testrange.
...

Expected Behavior:

tests pass.

How to reproduce it:

pytest --durations=0 -s -v tests/types/test_range.py

Additional information:

The tests only succeed after explicitly changing the owner of the relevant functions:

ALTER FUNCTION testschema.testrange(double precision, double precision) OWNER TO root;
ALTER FUNCTION testschema.testrange(double precision, double precision, text) OWNER TO root;

ALTER FUNCTION public.testrange(text, text, text) OWNER TO root;
ALTER FUNCTION public.testrange(text, text) OWNER TO root;

Even as root, the default function ownership prevents the tests from running.

Environment:

• OS: Huawei Cloud EulerOS 2.0
• Database: GaussDB
