A lot of work is currently being done on this, by multiple people, mostly not including me, and a lot of good progress is being made. But it's not exactly ready to ship, nor will it be any time soon. I think we can run a 1-client pgbench without crashing the server at this point, if you tweak the configuration a little bit and don't do anything fancy like, say, try to roll back a transaction. :-) -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
