According to ShmemIndexEnt struct:
/* this is a hash bucket in the shmem index table */
typedef struct
{
char key[SHMEM_INDEX_KEYSIZE]; /* string name */
void *location; /* location in shared mem */
Size size; /* # bytes requested for the structure */
Size allocated_size; /* # bytes actually allocated */
} ShmemIndexEnt;
The unit is bytes. A patch is attached to add such information.
