      Description

      A weird corner case, but it seems like you cannot have an extension column with the name "row". Blows up with:

      Caused by: java.sql.SQLException: error while executing SQL "select stream * from orders EXTEND (row varchar)": parse failed: Encountered "row" at line 1, column 37.
      Was expecting one of:
      <IDENTIFIER> ...
      <QUOTED_IDENTIFIER> ...
      <BACK_QUOTED_IDENTIFIER> ...
      <BRACKET_QUOTED_IDENTIFIER> ...
      <UNICODE_QUOTED_IDENTIFIER> ...

      Any other name seems to work (but not sure where to check for this in the code).
