I checked your fixes and I think it's OK. 
Finally, please move the doc fixes to patch B in order to separate patches
completely.

Your comment looks good, thanks.
In the previous version pgbench starts benchmarking even if some connections fail.
And users can notice the connection failure by stderr output.
Hence the current specification may be enough.
If you agree, please remove the following lines:

```

+				 * coldly exiting with an error message.
```

Could you tell me which patch you mention? Basically I agree what you say,
but I want to check it.
