Is it possible to have a variable number of parameters in an IN clause in a

Or do I need a constant number of parameters in there to be able to re-use
the prepared statement?
If it were possible, the best way to do that design-wise would be to have a
single parameter which was array-typed or relation-typed and then do a join on
it, like this:
select x.* from Table as x inner join ? as y using (Col1)
Otherwise, the closest thing would be to stuff the parameters in a temporary
table and then use that for the join in a subsequent select.
