Allowed choosing the IN-list data structure type

[avalente]

Currently it is impossible to interact with PostgreSQL advanced data types such as arrays because vectors are intercepted for the IN clause expansion. The set data type seems more suitable (after all, semantically it is a set membership test), but I made it configurable. I didn't change the default, however: if you want to change the behaviour you have to pass an explicit option.

I've dealt with this issue before, and an alternate solution that came to mind was naming the parameter such that it ended with "..." to indicate that it should be expanded into top-level items.

--- name: test
SELECT * FROM test WHERE x IN (:foo...) AND y = :bar

then query as (test ... {:foo... [1 2 3] :bar [2 3 4]})

Thoughts on that approach instead.
