Hmm, I think the parallel vacuum would help for heavy workloads like a big table with multiple indexes. In your test result, all executions are completed within 1 sec, which seems to be one use case that the parallel vacuum wouldn't help. I suspect that the table is small, right? Anyway I'll also do performance tests. Regards, -- Masahiko Sawada NIPPON TELEGRAPH AND TELEPHONE CORPORATION NTT Open Source Software Center
