em, we do not support get-instances-by-range queries,
but get-instance-by-value should be fine, as long as serialized
representation of list is same.

works in db-postmodern too, and i guess should work with clsql.

so either Frank has problems with some special form of lists,
or maybe he means that it's get-instances-by-range which is broken.
