I'm not sure what you mean by false positives. The patch just shows a
HINT, where before there was none. It's possible for any number of
reasons that it isn't the most useful possible suggestion, since
Levenshtein distance is used as opposed to any other scheme that might
be better sometimes. I think that the hint given is a generally useful
piece of information in the event of an ERRCODE_UNDEFINED_COLUMN
error. Obviously I think the patch is worthwhile, but fundamentally
the HINT given is just a guess, as with the existing HINTs.
