Perhaps the name of 'ColId' should be changed then.  At least to me that
comes across as 'Column Identifier', and apparently some others thought
it wasn't appropriate for user names (UserId existed and was mapped to
ColId prior to my patch).  Personally, I'd just like it to be
consistent, when I was looking at how to add the grammar for group
ownership group names were identified in one place as 'ColId' and another
as 'UserId', iirc.
