A followup to the original paper. Most importantly, I identified the cause for the drop on the graph after the 30 clients, which appeared to be the debugging version of malloc(3) in libc. Also there are some updates on the patches. New version of the paper is available at https://www.kib.kiev.ua/kib/pgsql_perf_v2.0.pdf The changes are marked as 'update for version 2.0'.
