I choose my words poorly. A discussion arose regarding the 7.4
protocol changes. I suggested looking forward to allow for a 2PC
implementation. Satoshi Nagayasu remarked about the work done on 2PC
and posted a link to patches:

http://snaga.org/pgsql/pgsql-20021025.tgz

The thread was here:

http://archives.postgresql.org/pgsql-hackers/2002-11/msg00143.php

Various people critiqued the work that had been done - protocol change
instead of a purely statement-driven implementation, the use of 2PC
for sync. replication, etc. And that was the last (and first, IIRC)
post from Satoshi Nagayasu. I was worried that PostgreSQL lost the
opportunity to have a 2PC implementation, because no one followed up,
allowing it to die on the vine.

I have learned from Rod Taylor that lack of posts on hackers doesn't
mean lack of work:

"They weren't ready to be committed at the time, nor are they now.
The hardest parts are still to come (resume, forget, etc.).
I believe he is still working on the third phase:

So I stand corrected.
