I think this is a good thing to be concerned about, but I'm not sure
what to make of it either. We could of course decide that -c implies
--no-psqlrc after all, for backward compatibility reasons. That would
be sort of strange because then psql -c A -f B will imply --no-psqlrc
but psql -f B will not. And that doesn't seem great either. I'm
inclined toward thinking we should just accept that some people will
need to update their scripts, but if that turns out to make enough
people unhappy then I may regret thinking that.
