Re: Avoiding inadvertent debugging mode for pgbench

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           not tested
Documentation:            tested, passed

Did a quick review of this one; CFbot is now happy, local regression tests all pass.

I think the idea here is sane; it's particularly confusing for some tools included in the main distribution to have
differentsemantics, and this seems low on the breakage risk here, so worth the tradeoffs IMO. 

The new status of this patch is: Ready for Committer
