I just wasted some time puzzling over strange results from pgbench. I eventually realized that I'd been testing against the wrong server, because rather than "-p 65432" I'd typed "-P 65432", thereby invoking the recently added --progress option. pgbench has no way to know that that isn't what I meant; the fact that both switches take integer arguments doesn't help.
To fix this, I propose removing the -P short form and only allowing the long --progress form. I won't argue that this feature is completely useless, but for sure it's not something I'd want more often than once in a blue moon. So I think it does not need to have a short form; and for sure it doesn't need a short form that's so easily confused with a commonly used switch.
