Um, sure!

My comments about the patch I submitted in bug 4819 indicate that it breaks bug
4810, so I'm not sure we can use it.  Honestly, I don't remember much about
these patches now, so I'd have to go back and review everything.

What, you can't keep up with the thousands of changes? :)  I can't either.  But
yeah, according to doc/README.developer, it was deprecated sometime around
9/14/2009 r29897 when the column functions started doing the check_col() checks
internally.

I have a capture file I might be able to post ... I will need to scrub it first
though.
