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 :)
