That's hilarious.
But, a command-line option seems more convenient.
It also seems entirely sufficient. The comments above suggest that it
would take too long to type the option, but any PG developers who are
worried about the speed difference surely know how to create shell
aliases, shell functions, shell scripts, ... and if anyone's really
concerned about it, we can provide a short form for the option.
