Hm, I think it's just the diff thats miss-leading there. It correctly marks the "int i" line as "removed" with a "-", but for some reason marks the "i = 0" line (and its successors) with a "!", although they're removed too, and not modified.

I've added the "-r" option to the list of pgbench options in pgbench.sgml and also added a short section that shows how the output looks like, similar to how things are done for the "-l" option.

Will do from now on.

Updated patch is attached. I've also pushed this as branch "pgbench_statementlatency" to git://github.com/fgp/postgres.git
