I disagree with making this error message lie about what the test was.
Clearly we need to s/3, 1/1, 3/ but I don't think the number should
be different from what we actually allow.

Having said that, maybe there's a case for requiring 4 columns now.
I agree it's pretty unlikely that current releases would see a pre-9.4
server on the other end of the line.
