+ParallelMain(Datum main_arg) { .. + /* + * Now that we have a resource owner, we can attach to the dynamic + * shared memory segment and read the table of contents. + */ + seg = dsm_attach(DatumGetInt32(main_arg)); Here, I think DatumGetUInt32() needs to be used instead of DatumGetInt32() as the segment handle is uint32.
