Re: Print latency percentiles in pgbench

Hi Roman,

> POC-patch attached, any feedback would be appreciated!

Thanks for working on this. I've started with the documentation part
of the patch, on master at 30faf13889b.

The doc changes re-indent some existing text without changing it:

- the <varlistentry> and <term> lines of --log-prefix,
- the "when neither --progress, --rate, nor --latency-limit" lines,
- the whole paragraph on retries ("The main report contains the
number of failed transactions...").

The new --latency-percentiles varlistentry is also indented one level
deeper than the entries around it, so --log-prefix now has its
<varlistentry> and <term> at a different depth from its <listitem>.

Because of this, the doc diff is +57/-12, while git diff -w shows
+47/-2. Could you keep the existing indentation and indent the new
entry like its neighbours, so that only the real changes remain?

Regards,
Don Hoang
