Fair enough, but this patch arose from the discussion that the collation
patch had a lot of hunks that just changed (typeid, typmod) to (typeid,
typmod, collation) and that that could be isolated by collecting those
into a common data structure. We can abandon this line of thought and
I'll go back to my original project, but I thought others who are
thinking about improving typmods could also benefit from this work.
