No. It would be a major surgery on the internals. See the article for my comment at the attempt to do this with the Zheap project:

I think there is a new project from the Postgres community. They try to replace the storage engine to solve the inefficiency caused by MVCC

Depending on the use case, I'd consider a foreign data wrapper.

Shame that zheap seems to have fizzled out. Do you think there's any prospect of it being resurrected and eventually mainlined?
