Address ORA-00923 error by quoting a reserved word "SIZE"

Raise `ArgumentError` when an invalid form is passed to `Date#to_time`

Extract `extract_schema_qualified_name` method

Extract `arel_visitor` and move up to the abstract adapter

* Use separate stream handler builders for easy override and testing.
* Fix worker pool execution that was silently failing since it only
  expected connection receivers.

Sparked by code in #24162.

Ruby 2.4 introduces `Array#sum`, but it only supports numeric elements,
breaking our `Enumerable#sum` which supports arbitrary `Object#+`.
To fix, override `Array#sum` with our compatible implementation.

Native Ruby 2.4:

    %w[ a b ].sum
    # => TypeError: String can't be coerced into Fixnum

With `Enumerable#sum` shim:

    %w[ a b ].sum
    # => 'ab'

We tried shimming the fast path and falling back to the compatible path
if it fails, but that ends up slower even in simple causes due to the cost
of exception handling. Our only choice is to override the native `Array#sum`
with our `Enumerable#sum`.

Avoid a string value truncation in uniqueness validation

Inspired by Arnau Siches' [ISO8601 gem](https://github.com/arnau/ISO8601/)
and rewritten by Andrey Novikov with suggestions from Andrew White. Test
data from the ISO8601 gem redistributed under MIT license.

(Will be used to support the PostgreSQL interval data type.)

Primary key should be `NOT NULL`

* Rewrite docs
* Support blocks in addition to method names and Proc args
* Check for valid arguments
* Convert `periodically :method_name` to Proc callbacks
* Drop periodic runner methods from the worker pool
* Ensure we clear active periodic timers after shutdown

Fix isolated test failures due to referencing ActiveRecord::Tasks::DatabaseAlreadyExists before another test happened to make it available

Don't create new arrays when trying to compute non_empty_predicates for ast generation

* Switch to keyword args where we can without breaking compat.
* Use add_table_options! for :options, too.
* Some code polish.

Don't create new arrays when trying to compute non_empty_predicates for where clause predicate. Get a 3-4% improvement in AST generation.

Fix forced cache miss for fetch when called without a block.

'force: true' option is set.
- Added tests for the same.

Fix typos in ActionCable Channel [ci skip]

Railties' `config` method instatiates a Rails::Railtie::Configuration
object. Rails::Configuration is not used in this file.

The patch does not replace the file being required with the one for
Rails::Railtie::Configuration because that one is autoloaded. See the
spot where this patch changes double quotes with single quotes.

Rails::Railtie::Configuration does depend on Rails::Configuration, and
it requires it accordingly.
