vfoo has three fields: oid, id, and name.  If you INSERT without a
column list, the values are assigned to the columns in order: oid=1,
id='test1', name=NULL.  Are you suggesting that the insert should
ignore oid since its source is a system column?  I'm not sure such
behavior would be desirable because of the inconsistency it would
introduce: sometimes values would be assigned to the displayed
columns in order, but other times one or more of those columns might
be implicitly skipped.
