Great.  Rumour has it there is some HOT transaction code in there, among
other things.

We may find that that HOT transaction code is the same as our
transaction code, which I guess would mean ours is HOT too.

I wonder when they implemented theirs?  Basically...is their's based on
old technology/concepts, while ours is based on newer ones?

Reminds me of the guy who said our MVCC was a leader in database
technology.  He did not realize is was only one person, Vadim, who did
the whole thing.

Amazing when just one of our developers makes the commercial db's look
like they are standing still.

     Maybe it's based on the same technology. If the've used a similar (HOT)
     transactional concept for tuples, based legally on the PG technique
     released under the BSD license years ago, they might have come to the
     same conclusion. That'd mean - well - OLD concepts like ours.

     Truth remains truth.

Yes, MVCC was natural for us.

(redundant, but what the heck)

Their "multi-generational" concurrency control sure sounds just like
MVCC.

Apparently they were formed out of DEC in 1985, with the notion of
doing a "multi-generational" model from the beginning.

I don't know enough Postgres history to answer.  Obviously, MVCC
is new but the way that tuples are stored, which made MVCC fairly
simple to implement (for Vadim, at least!), has been part of 
Postgres from the beginning.  

And, again, my information on Interbase comes from a VERY quick
read of docs and a white paper found on their site, take my 
quick-hit analysis with a grain of salt, please!
