Anything in primnodes should never need a TypeName.  Post-parse-analysis
representation of type info is as a pg_type Oid.  If you think you need
something else, let's have a discussion about why.  (Perhaps you need to
split XmlExpr into two different node types, one for raw grammar output
and one for parse-analysis output?)
