数组比较

Question

select preference.id from preference where  
--array(select id from date_etl where local_date >= '02/01/2011' and local_date <= '02/25/2011') && date_etl_array  --option 3 gives error, do not know why? and how to fix it?  
--array(select id from date_etl where local_date >= '02/01/2011' and local_date <= '02/25/2011') && '{1342715,1342739}'  --option 2 runs with no error  
--date_etl_array && '{1342715,1342739}'  --option 1 runs with no error

=#\d preference
date_etl_array              | integer[]                   |  

选项1和选项2正在运行，但选项3没有，我不知道为什么以及如何解决它。 我正在尝试与选项3进行数组比较

Answer 1

无效，因为它将bigint[]与integer[]进行了比较。
