Обсуждение: Persistent main memory Storage Manager

Does anyone know if the code for the Main Memory Storage Manager is
available somewhere (Berkeley??)?
Also, in released versions, MM.c is included but not used, does anyone
know if it should work if we define the STABLE_MEMORY_STORAGE, or do a
lot  coding has to be done for it to work?
Please CC to my e-mail if you are answering this mail ( otherwise I
won;t read it til the Digest)..
Any information on the Main Memory Storage Manager would be greatly
appreciated.

Thanks a lot,

Diego Montenegro

Actually, I removed that file a few days ago because I didn't see any
point in updating it to match the recent smgr API changes.  Seems very
unlikely that it'd still work, given that it hasn't been maintained for
so many years.

It's unclear to me why anyone would bother with it anyway.  Putting
$PGDATA on a RAM disk should have approximately the same effect.
