Comment(by strk):

 The core deserializer uses allocators set in the rt_context.
 In the rt_pg case, this is palloc, which is supposed to release the memory
 when the associated pool goes out of scope.

 Now, the scope might be wider than you'd like, in which case it's fine to
 release manually, but it shouldn't live cross a single query.
