I see the problem only with one specific case – when the method is `where_object_changes` and the serializer is YAML. Which is a default configuration.
I see there are 6 types of queries with a numeric value for `where_object_changes` and `where_object` (grabbed from `version_spec.rb`):
```
.where_object_changes
N1
SELECT "versions".* FROM "versions" WHERE "versions"."item_id" = 1 AND "versions"."item_type" = 'Widget' AND (object_changes @> '{"an_integer":[1]}') ORDER BY "versions"."created_at" ASC, "versions"."id" ASC
N1
SELECT "versions".* FROM "versions" WHERE "versions"."item_id" = 1 AND "versions"."item_type" = 'Widget' AND ("versions"."object_changes" ILIKE '%
an_integer:
- 1
%' OR "versions"."object_changes" ILIKE '%
an_integer:
-%
- 1
%') ORDER BY "versions"."created_at" ASC, "versions"."id" ASC
N3
SELECT "versions".* FROM "versions" WHERE "versions"."item_id" = 1 AND "versions"."item_type" = 'Widget' AND (((object_changes->>'an_integer' ILIKE '[1,%') OR (object_changes->>'an_integer' ILIKE '[%,1]%'))) ORDER BY "versions"."created_at" ASC, "versions"."id" ASC
.where_object
N4
SELECT "versions".* FROM "versions" WHERE (object @> '{"an_integer":1}')
N5
SELECT "versions".* FROM "versions" WHERE (object->>'an_integer' = '1')
N6
SELECT "versions".* FROM "versions" WHERE ("versions"."object" ILIKE '%
an_integer: 1
%')
```
The only problematic one is N2. It incorrectly matches `object_changes` like
```
