This is related with #27680.
Since `where_values_hash` keys constructed by `where` are string, so we
need `stringify_keys` to `create_with_value` before merging it.

The `find_each`, `find_in_batches` and `in_batches` APIs usually operate
on large numbers of records, where it's preferable not to load them all
into memory at once.
If the query cache is enabled, it will hold onto the query results until
the end of the execution context (request/job), which means the memory
used is still proportional to the total number of records. These queries
are typically not repeated, so the query cache isn't desirable here.

When `order` is given a hash, the keys are currently assumed to be
attribute names and are quoted as such in the query, which makes it
impossible to pass an expression instead:
Post.order("LENGTH(title)" => :asc).last
# SELECT `posts`.* FROM `posts` ORDER BY `posts`.`LENGTH(title)` DESC LIMIT 1
If the key is an `Arel::Nodes::SqlLiteral`, we now use it directly in
the query. This provides a way to build a relation with a complex order
clause that can still be reversed with `reverse_order` or `last`.

Regexp#match? should be considered to be part of the Ruby core library. We are
emulating it for < 2.4, but not having to require the extension is part of the
illusion of the emulation.

- CollectionAssociation#select was removed in
https://github.com/rails/rails/pull/25989 in favor of
QueryMethods#select but it caused a regression when passing arguments
to select and a block.
- This used to work earlier in Rails 4.2 and Rails 5. See gist
https://gist.github.com/prathamesh-sonpatki/a7df922273473a77dfbc742a4be4b618.
- This commit restores the behavior of Rails 4.2 and Rails 5.0.0 to
allow passing arguments and block at the same time but also deprecates
it.
- Because, these arguments do not have any effect on the output of
select when select is used with a block.
- Updated documentation to remove the example passing arguments and
block at the same time to `CollectionProxy#select`.

All indentation was normalized by rubocop auto-correct at 80e66cc4d90bf8c15d1a5f6e3152e90147f00772.
But comments was still kept absolute position. This commit aligns
comments with method definitions for consistency.

Recently, the Rails team made an effort to keep the source code consistent, using Ruboco
(bb1ecdcc677bf6e68e0252505509c089619b5b90 and below). Some of the case
statements were missed.
This changes the case statements' formatting and is consistent with changes
in 810dff7c9fa9b2a38eb1560ce0378d760529ee6b and db63406cb007ab3756d2a96d2e0b5d4e777f8231.

A few have been left for aesthetic reasons, but have made a pass
and removed most of them.
Note that if the method `foo` returns an array, `foo << 1`
is a regular push, nothing to do with assignments, so
no self required.

In 5.0 we use bind parameters for limit and offset, while in 4.2 we used
the values directly. The code as it was written assumed that limit and
offset worked as `LIMIT ? OFFSET ?`. Both Oracle and SQL Server have a
different syntax, where the offset is stated before the limit. We
delegate this behavior to the connection adapter so that these adapters
are able to determine how the bind parameters are flattened based on
what order their specification has the various clauses appear.
Fixes #24775

<"undefined method `limit_value' for {:title=>\"Rails\"}:Hash">
- Now it shows following error message.

ArgumentError: You have passed Hash object to #or. Pass an ActiveRecord::Relation object instead.

This still isn't as separated as I'd like, but it at least moves most of
the burden of alias mapping in one place.

When you are using scopes and you chaining these scopes it is hard to
know which are the values that are incompatible. This way you can read
the message and know for which values you need to look for.

DEPRECATION WARNING: Time columns will become time zone aware in Rails 5.1. This
still causes `String`s to be parsed as if they were in `Time.zone`,
and `Time`s to be converted to `Time.zone`.
To keep the old behavior, you must add the following to your initializer:
config.active_record.time_zone_aware_types = [:datetime]
To silence this deprecation warning, add the following:
config.active_record.time_zone_aware_types << :time

We currently generate an unbounded number of prepared statements when
`limit` or `offset` are called with a dynamic argument. This changes
`LIMIT` and `OFFSET` to use bind params, eliminating the problem.
`Type::Value#hash` needed to be implemented, as it turns out we busted
the query cache if the type object used wasn't exactly the same object.
This drops support for passing an `Arel::Nodes::SqlLiteral` to `limit`.
Doing this relied on AR internals, and was never officially supported
usage.
Fixes #22250.

Some backends allow `LIMIT 1,2` as a shorthand for `LIMIT 1 OFFSET 2`.
Supporting this in Active Record massively complicates using bind
parameters for limit and offset, and it's trivially easy to build an
invalid SQL query by also calling `offset` on the same `Relation`.
This is a niche syntax that is only supported by a few adapters, and can
be trivially worked around by calling offset explicitly.
