No, the complaint is that the wrong thing is shown --- but I don't
know what's showing it; aclcheck_error() certainly doesn't.

There's a separate conversation to be had perhaps about whether
aclcheck_error's standard message *should* include the role name
whose permissions were checked.  I have a vague feeling that that
omission was intentional, but it was so long ago that I don't
recall for sure.  It seems like something that'd be good to show
in more complicated situations with views, security definer
functions, etc.
