Can the MVCC implementation be swapped via Postgres extensions?

  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: https://wiki.postgresql.org/wiki/Zheap https://wiki.postgresql.org/wiki/Zheap

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

  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 https://github.com/orioledb/orioledb https://github.com/orioledb/orioledb

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