Also, `reset_column_information` is unnecessary since `reset_table_name`
does that too.

regression for fixture loading
d8d6bd5 makes fixture loading to bulk statements by using
`execute_batch` for sqlite3 adapter. But `execute_batch` is slower and
it caused the performance regression for fixture loading.
In sqlite3 1.4.0, it have new batch method `execute_batch2`. I've
confirmed `execute_batch2` is extremely faster than `execute_batch`.
So I think it is worth to upgrade sqlite3 to 1.4.0 to use that method.

Cache database version in schema cache

* The database version will get cached in the schema cache file during the
schema cache dump. When the database version check happens, the version will
be pulled from the schema cache and thus avoid querying the database for
the version.
* If the schema cache file doesn't exist, we'll query the database for the
version and cache it on the schema cache object.
* To facilitate this change, all connection adapters now implement
#get_database_version and #database_version. #database_version returns the
value from the schema cache.
* To take advantage of the cached database version, the database version check
will now happen after the schema cache is set on the connection in the
connection pool.

`delete_all`
This partly reverts #35617.
#35617 includes unused code (for `InsertStatement`) and re-using query
annotation for `update_all` and `delete_all`, which has not been
discussed yet.
If a relation has any annotation, I think it is mostly for SELECT query,
so re-using annotation by default is not always desired behavior for me.
We should discuss about desired behavior before publishing the
implementation.

Fix callbacks on has_many :through associations

| | | | | |
When adding a child record via a has_many :through association,
build_through_record would previously build the join record, and then
assign the child record and source_type option to it. Because the
before_add and after_add callbacks are called as part of build, however,
this caused the callbacks to receive incomplete records, specifically
without the other end of the has_many :through association. Collecting
all attributes before building the join record ensures the callbacks
receive the fully constructed record.

Type cast falsy boolean symbols on boolean attribute as false

Before 34cc301, type casting by boolean attribute when querying is a
no-op, so finding by truthy boolean string (i.e.
`where(value: "true") # => value = 'true'`) didn't work as expected
(matches it to FALSE in MySQL #32624). By type casting is ensured, a
value on boolean attribute is always serialized to TRUE or FALSE.
In PostgreSQL, `where(value: :false) # => value = 'false'` was a valid
SQL, so 34cc301 is a regresson for PostgreSQL since all symbol values
are serialized as TRUE.
I'd say using `:false` is mostly a developer's mistake (user's input
basically comes as a string), but `:false` on boolean attribute is
serialized as TRUE is not a desirable behavior for anybody.
This allows falsy boolean symbols as false, i.e.
`klass.create(value: :false).value? # => false` and
`where(value: :false) # => value = FALSE`.
Fixes #35676.

Fix preloader to never reset associations in case they are already loaded

This patch fixes the issue when association is preloaded with a custom
preload scope which disposes the already preloaded target of the
association by reseting it.
When custom preload scope is used, the preloading is now performed into
a separated Hash - #records_by_owner instead of the association.
It removes the necessaty the reset the association after the preloading
is complete so that reset of the preloaded association never happens.
Preloading is still happening to the association when the preload scope
is empty.

`TRUNCATE TABLE posts` also resets `AUTO_INCREMENT`. If newly created a
post, it is wrongly associated with remaining tagging records.
To un-associate remaining tagging record, use `post.create_tagging!`
instead.
Fixes #35751.
