pgsql=# SELECT * FROM sal_emp WHERE 10000 = ANY (pay_by_quarter);
name | pay_by_quarter | schedule
-------±--------------------------±------------------------------------------
Bill | {10000,11000,9000,13000} | {{meeting,lunch},{training,presentation}}
Frank | {10000,10000,10000,10000} | {{breakfast,training},{meeting,lunch}}

可以的，in列表系统也会转成any，可以通过执行计划观察。
