message:
  Bug#27249 table_wild with alias: select t1.* as something

  Aliases to table wildcards are silently ignored, but they should
  not be allowed as it is non-standard and currently useless. There
  is not point in having a alias to a wildcard of column names.

  The solution is to rewrite the select_item rule so that aliases
  for table wildcards are not accepted.
