Re: PREPARE query with IN?

[Filip Rembiałkowski <plk.zuber@xxxxxxxxx>]

filip@filip=# prepare sth(int[]) as select * from ids where id = ANY($1);
PREPARE

filip@filip=# execute sth('{1,2,3}');
 id |   t
----+-------
  1 | eenie
  2 | menie
  3 | moe
(3 rows)

Is it possible to prepare a query with the IN clause in a meaningful
way? I could probably do it with a hard-coded number of arguments, like
"SELECT x FROM t WHERE y IN ($1, $2, $3)" but that kind of misses the
point of using IN for my needs.

In any case, it would probably be a good idea to add a sentence about it
on http://www.postgresql.org/docs/8.3/interactive/sql-prepare.html since
I'm probably not the first one to ask about it :)
