My first thought when looking at this thread/patch was that something like
"read-write" might be a bit long for a psql prompt. I probably would've
chosen something like "r" or "ro" for read-only and "rw" for read-write. I
suppose you could argue that those are more difficult to see, and this
seems particularly useful when you want to be sure that you won't
inadvertently write any data.
