It's not just pfree. Offhand, there's also repalloc, GetMemoryChunkSpace and GetMemoryChunkContext too. I am interested in a bump allocator for tuplesort.c. There it would be used in isolation and all the code which would touch pointers allocated by the bump allocator would be self-contained to the tuplesorting code. What use case do you have in mind?
