#33363 has two regressions. First one is that `insert_fixtures_set` is
failed if flags is an array. Second one is that connection flags are not
restored if `set_server_option` is not supported.

This reverts commit eb807384c81a6e086b17a576755e992e6c4c685e.
If the current scope is affected by the `unscoped` block, `all` won't be
the same with `spawn`.

Related #31201.
If creating custom primary key (like a string) in SQLite, it would also
create an internal index implicitly which named begin with "sqlite_".
It need to be hidden since the internal object names are reserved and
prohibited for public use.
See https://www.sqlite.org/fileformat2.html#intschema
Fixes #33320.

Fix default value for mysql time types with specified precision

The TIME, DATETIME, and TIMESTAMP types [have supported](https://mariadb.com/kb/en/library/microseconds-in-mariadb/)
a fractional seconds precision from 0 to 6.
Default values from time columns with specified precision is read
as `current_timestamp(n)` from information schema.
rake `db:schema:dump` produces `schema.rb` **without** default values for time columns with the specified precision:
t.datetime "last_message_at", precision: 6, null: false
rake `db:schema:dump` produces `schema.rb` **with** default values for time columns with the specified precision:
t.datetime "last_message_at", precision: 6, default: -> { "current_timestamp(6)" }, null: false

Currently, the seen object cache is shared if join nodes have the same
target class. But it is a wrong assumption, we can't share the seen
object cache between different join nodes (e.g. `:readonly_account` and
`:accounts` have the same target class `Account`, but the instances
have the different state `readonly`).
Fixes #26805.
Closes #27737.

Support readonly option in SQLite3Adapter

Readonly sqlite database files are very useful as a data format for
storing configuration/lookup data that is too complicated for YAML
files. But since such files would typically be committed to a source
control repository, it's important to ensure that they are truly safe
from being inadvertently modified. Unfortunately using unix permissions
isn't enough, as sqlite will "helpfully" add the write bit to a database
file whenever it's written to.
sqlite3-ruby has supported a `:readonly` option since version 1.3.2 (see
https://github.com/sparklemotion/sqlite3-ruby/commit/c20c9f5dd2990042)
This simply passes that option through to the adapter if present in the
config hash. I think this is best considered an adapter-specific option
since no other supported database has an identical concept.

Now that `allocate` is removed, we need to define attribute methods in
all "init" methods.

If someone calls allocate on the object, they'd better also call an
initialization routine too (you can't expect allocate to do any
initialization work). Before this commit, AR objects that are
instantiated from the database would call `define_attribute_methods`
twice.

`extend Aggregations::ClassMethods` since 657060b.

This commit speeds up allocating homogeneous lists of AR objects. We
can know if the result set contains an STI column before initializing
every AR object, so this change pulls the "does this result set contain
an STI column?" test up, then uses a specialized instantiation function.
This way we only have to check for an STI column once rather than N
times.
This change also introduces a new initialization function that is meant
for use when allocating AR objects that come from the database. Doing
this allows us to eliminate one hash allocation per AR instance.
Here is a benchmark:
```ruby
require 'active_record'
require 'benchmark/ips'
ActiveRecord::Base.establish_connection adapter: "sqlite3", database: ":memory:"
ActiveRecord::Migration.verbose = false
ActiveRecord::Schema.define do
create_table :users, force: true do |t|
t.string :name
t.timestamps null: false
end
end
class User < ActiveRecord::Base; end
2000.times do
User.create!(name: "Gorby")
end
Benchmark.ips do |x|
x.report("find") do
User.limit(2000).to_a
end
end
```

`composed_of` is a fairly rare method to call on models. This commit
adds the `Aggregations` module to models that call `composed_of` so that
models that *don't* call `composed_of` don't need to instantiate the
`aggregation_cache` hash. This saves one hash allocation per model
instance that doesn't use `composed_of`

The "join" affix in `table_alias_for` was added 12 years ago at 02d3444
to address poor alias tracking.
`AssociationScope` no longer uses the "join" suffixed alias since
0408e21 and had been removed at a1ec8b5.
`table_alias_for` is the last place that using the useless legacy
suffixed alias, but we can't remove the suffix since some test cases
directly refers the alias name by `where` with string literal, so at
least removing the suffix would break our test cases.
(e.g. https://github.com/rails/rails/blob/b2eb1d1c55a59fee1e6c4cba7030d8ceb524267c/activerecord/test/cases/associations/has_and_belongs_to_many_associations_test.rb#L699-L731).
