Hi,

The attached patch fixes a minor type mismatch in `test_shm_mq_main()`.

The argument passed to `dsm_attach()` is expected to be a `uint32`, but the
code currently uses `DatumGetInt32()` to extract it from the `Datum`
argument. This can lead to incorrect behavior when the high bit is set, as
'unable to map dynamic shared memory segment'.

This patch changes it to use `DatumGetUInt32()` to match the expected type
and ensure correctness.


Thanks,  
Jianghua Yang
