PostgreSQL & JDBC set array of ints using `setArray` throw an exception "cannot cast type integer[] to integer"

Question

How do I set an array of integers in JDBC (prepared statement with setArray for an in clause?

String query = "SELECT * FROM table WHERE id IN (?)";
// other things.
// ArrayList<Integer> some_ids;
preparedStatement.setArray(1, conn.createArrayOf("INTEGER", some_ids.toArray()));

It compiles, but executing returns this from Postgres.

ERROR: cannot cast type integer[] to integer

In PostgreSQL You have to use = ANY(?) instead of IN (?)

"SELECT * FROM table WHERE id = ANY(?)";

Take a look at this : 9.21.3. ANY/SOME (array)
