Follow up of #39255. Previously aggregation functions only use the model's attribute types on the relation for type cast, this will be looking up association's attribute and type caster if a column name is table name qualified. Fixes #39248.

A previous change made singleton methods eagerly define their relation methods if it shared a name with a method on Kernel. This caused issues with a few methods which were both defined on Kernel and on AcitveRecord::Relation. This commit avoids defining the method if it exists on AR::Relation.

Since we're checking `serializable?` in the new `HomogeneousIn` `serialize` will no longer raise an exception. We implemented `unchecked_serialize` to avoid raising in these cases, but with some of our refactoring we no longer need it. I discovered this while trying to fix a query in our application that was not properly serializing binary columns. I discovered that in at least 2 of our active model types we were not calling the correct serialization. Since `serialize` wasn't aliased to `unchecked_serialize` in `ActiveModel::Type::Binary` and `ActiveModel::Type::Boolean` (I didn't check others but pretty sure all the AM Types are broken) the SQL was being treated as a `String` and not the correct type. This caused Rails to incorrectly query by string values. This is problematic for columns storing binary data like our emoji columns at GitHub. The test added here is an example of how the Binary type was broken previously. The SQL should be using the hex values, not the string value of "🥦" or other emoji. We still have the problem `unchecked_serialize` was supposed to fix - that `serialize` shouldn't validate data, just convert it. We'll be fixing that in a followup PR so for now we should use `serialize` so we know all the values are going through the right serialization for their SQL.

This is the opposite direction of #39039. #39111 fixes `minimum` and `maximum` on date columns with type casting by column type on the database. But column type has no information for time zone aware attributes, it means that attribute type should always be precedence over column type. I've realized that fact in the related issue report #39248. I've reverted the expectation of #39039, to make time zone aware attributes works.

Per [this discussion][arel-discussion] on the discourse forum, this is an addition to Arel for supporting `@>` (contains) and `&&` (overlaps) operators in PostgreSQL. They are useful for GIN-indexed data such as a `jsonb` or array column. [arel-discussion]: https://discuss.rubyonrails.org/t/what-has-happened-to-arel/74383/51

Profiling our application boot shows this method at 1.3% of boot time: ``` ActiveRecord::AttributeMethods::ClassMethods#dangerous_attribute_method? (/tmp/bundle/ruby/2.7.0/bundler/gems/rails-4919b459d946/activerecord/lib/active_record/attribute_methods.rb:100) samples: 5 self (0.0%) / 866 total (1.3%) callers: 866 ( 100.0%) ActiveRecord::AttributeMethods::PrimaryKey::ClassMethods#dangerous_attribute_method? callees (861 total): 861 ( 100.0%) ActiveRecord::AttributeMethods::ClassMethods#method_defined_within? ``` [A quick benchmark](https://gist.github.com/casperisfine/0ce1161253ab643f5f15ff63e901b818) shows that we can make it 2 to 3 times faster by precomputing the list of dangerous methods, and doing a simple set lookup. Of course this isn't strictly equivalent, as it's no longer dynamic, so if you include a module in `AR::Base` after the list was computed, new dangerous methods won't be considered. But at the same time, if the list was already computed, it means you defined attribute methods before AR::Base was fully initialized. `dangerous_class_method?` is pretty much invisible on profiles, but I applied the same optimization to it for consistency's sake.

Follow up of #34122. Relation method call is relying on method_missing, but if `Kernel` has the same named method (e.g. `open`, etc), it will invoke Kernel's method since method_missing is not happened. To prevent that, eager generate relation methods if a method is the same name on `Kernel`. Fixes #39195.

Actually that result is odd and hard to predictable result to me, but we should not change the public behavior without deprecation cycle. I had not intended to break any apps, so I've restored the behavior. Fixes #39171.

It is possible to unscope only the column in the specified table. ```ruby posts = Post.joins(:comments).group(:"posts.hidden") posts = posts.where("posts.hidden": false, "comments.hidden": false) posts.count # => { false => 10 } # unscope both hidden columns posts.unscope(where: :hidden).count # => { false => 11, true => 1 } # unscope only comments.hidden column posts.unscope(where: :"comments.hidden").count # => { false => 11 } ``` Co-authored-by: NSlava Korolev <korolvs@gmail.com>

Follow-up to #39147 and #39168. By adding a new purpose-specific format, we avoid potential pitfalls from concatenating format strings. We also save a String allocation per Time attribute per inspect. The new format also includes a time zone offset for more introspective inspection.

This removes an optimization that `attr.in(range_object)` acts as `attr.between(range_object` which is deprecated over 5 years ago. `attr.in` will generate exactly IN clause even if a range object is passed. Use `attr.between` instead if BETWEEN clause is what want to get. Ref https://github.com/rails/arel/pull/333.

Some apps would expect that type cast is not evaluated at relation build time consistently. Context: https://github.com/kamipo/rails/commit/b571c4f3f2811b5d3dc8b005707cf8c353abdf03#r31015008 https://github.com/rails/rails/pull/34303 And also this removes extra grouping on IN clause behaved as before.

Some commits adds `**` to address kwargs warnings in Ruby 2.7, but `save` and `save!` are originally doesn't take positional arguments, so maintain both `*` and `**` is redundant. https://github.com/rails/rails/commit/6d68bb5f695414b1801c1c3952ef955a5b0b6c6a https://github.com/rails/rails/commit/09d7ce79750d08b6b9c64fd038eee285d0cbfd44 https://github.com/rails/rails/commit/51a7422c9f10cc75a3ef6bf9177324fc771d7ba4

In the past, we sometimes hit missing `Symbol#start_with?` and `Symbol#end_with?`. https://github.com/rails/rails/commit/63256bc5d7dd77b2cce82df46c53249dab2dc2a8 https://github.com/rails/rails/commit/a8e812964d711fa03843e76ae50f5ff81cdc9e00 So I proposed `Symbol#start_with?` and `Symbol#end_with?` to allow duck typing that methods for String and Symbol, then now it is available in Ruby 2.7. https://bugs.ruby-lang.org/issues/16348 Using `String#starts_with?` and `String#ends_with?` could not be gained that conveniency, so it is preferable to not use these in the future.

```ruby steve = Person.find_by(name: "Steve") david = Author.find_by(name: "David") relation = Essay.where(writer: steve) # Before relation.rewhere(writer: david).to_a # => [] # After relation.rewhere(writer: david).to_a # => [david] ``` For now `rewhere` only works for truly column names, doesn't work for alias attributes, nested conditions, associations. To fix that, need to build new where clause first, and then get attribute names from new where clause.

To change a NOT NULL constraint `reversible`. When changing a NOT NULL constraint, we use `ActiveRecord::ConnectionAdapters::SchemaStatements#change` method that is not reversible, so `up` and `down` methods were required. Actually, we can use `change_column_null` method if only one constraint changed, but if we want to change multiple constarints with ALTER QUERY, `up` and `down` methods were required.

Since 901d62c5, associations can only be autosaved once: after a record has been saved, `@new_record_before_save` will always be false. This assumes that records only transition to being persisted once, but there are two cases where it happens multiple times: when the transaction that saved the record is rolled back, and when the persisted record is later duplicated.

I supposed all aggregation functions will return numeric result in #39039, but that assumption was incorrect for `minimum` and `maximum`, if an aggregated column is non numeric type. I've restored type casting aggregated result for `minimum` and `maximum`. Fixes #39110.
