Description

I am having a problem with sql translation to Trino that results in a query with an identifier column.

  SELECT  numbers ,  animal ,  n ,  a 
FROM  ( 
VALUES 
  ( ARRAY [ 2 ,  5 ],  ARRAY [ 'dog' ,  'cat' ,  'bird' ]), 
  ( ARRAY [ 7 ,  8 ,  9 ],  ARRAY [ 'cow' ,  'pig' ]) 
)  AS  x  ( numbers ,  animals ) 
CROSS  JOIN  UNNEST ( numbers, 动物)  AS  t  ( n ,  a );

Research direction

Start by reproducing the supplied SQL translation to Trino and isolate the parser failure around ARRAY and identifier handling. Compare the reported error with the query structure; done means this query translates successfully without the failed 'identifier' rule.
