So are you expecting that if some one needs to retain dynamic segment's
till PM lifetime, they should call both dsm_keep_segment() and
dsm_keep_mapping()?
If we don't call both, it can lead to following warning:
postgres=# select dsm_demo_create('this message is from session-new', 1);
WARNING: dynamic shared memory leak: segment 1402373971 still referenced
