I have the following 

select *
from   employee AS e
where  (e.id) IN  (ARRAY[3,1]);

I have the following mistake
ERROR:  operator does not exist: integer = integer[]
LINE 3: where  (e.id) IN  (ARRAY[3,1]);                     ^
HINT:  No operator matches the given name and argument type(s). You might
need to add explicit type casts.

********** Error **********

ERROR: operator does not exist: integer = integer[]
SQL state: 42883
Hint: No operator matches the given name and argument type(s). You might
need to add explicit type casts.
Character: 45


Can anybody explain me?

Hello

this is not error, you cannot use predicate IN in this context

use =ANY instead

postgres=> select 10 = ANY(ARRAY[1,2,3]);?column?
----------f
(1 row)

postgres=> select 10 = ANY(ARRAY[1,2,3,10]);?column?
----------t
(1 row)

Regards
