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: http://snaga.org/pgsql/ -- Rod Taylor <[EMAIL PROTECTED]>" So I stand corrected.
