That would disable psql's tab completion, command editing, and history
altogether, which I doubt is what you want for production builds.
If we conclude we can't work around the testing issues for ancient
libedit, probably the right answer is to provide a switch to
disable just the test.  I've been trying to dance around that
conclusion, but maybe we should just do it and move on.
