Not sure how standard it is, but the docs[1] would suggest that it's
trying to following something. Microsoft's MSDN docs on ODBC[2] show a
reasonable similarity, the first Oracle doc I found[3] where similar as
well.
It just looks like a fixed set of numbers for a fixed set of conditions,
can't find any canonical definition about what it's really for though.
