There is no reason for the PG adapter to have a default limit of 255 on :string
columns. See this snippet from the PG docs:
Tip: There is no performance difference among these three types, apart
from increased storage space when using the blank-padded type, and a
few extra CPU cycles to check the length when storing into a
length-constrained column. While character(n) has performance
advantages in some other database systems, there is no such advantage
in PostgreSQL; in fact character(n) is usually the slowest of the
three because of its additional storage costs. In most situations text
or character varying should be used instead.

It was causing error when using `with_options` passing a lambda as its
last argument.
class User < ActiveRecord::Base
with_options dependent: :destroy do |assoc|
assoc.has_many :profiles, -> { where(active: true) }
end
end
It was happening because the `option_merger` was taking the last
argument and checking if it was a Hash. This breaks the HasMany usage,
because its last argument can be a Hash or a Proc.
As the behavior described in this test:
https://github.com/rails/rails/blob/master/activesupport/test/option_merger_test.rb#L69
the method will only accept the lambda, this way it will keep the expected behavior. See 9eaa0a34

citext makes it possible to use AR Hash finders for case-insensitive matching as sql UPPER/LOWER functions are not needed.

conflicting private method defined on its ancestors.
The problem is that `method_defined_within?(name, klass, superklass)`
only works correclty when `klass` and `superklass` are both `Class`es.
If both `klass` and `superklass` are both `Class`es, they share the
same inheritance chain, so if a method is defined on `klass` but not
`superklass`, this method must be introduced at some point between
`klass` and `superklass`.
This does not work when `superklass` is a `Module`. A `Module`'s
inheritance chain contains just itself. So if a method is defined on
`klass` but not on `superklass`, the method could still be defined
somewhere upstream, e.g. in `Object`.
This fix works by avoiding calling `method_defined_within?` with a
module while still fufilling the requirement (checking that the
method is defined withing `superclass` but not is not a generated
attribute method).
4d8ee288 is likely an attempted partial fix for this problem. This
unrolls that fix and properly check the `superclass` as intended.
Fixes #11569.

The `subclass_from_attrs` method is called even if the column specified by
the `inheritance_column` setting doesn't exist. This prevents setting associations
via the attributes hash if the association name clashes with the value of the setting,
typically `:type`. This worked previously in Rails 3.2.

Previously, this would give an `ArgumentError`:
class Issue < ActiveRecord::Base
enum :status, [:open, :finished]
end
Issue.open.build # => ArgumentError: '0' is not a valid status
Issue.open.create # => ArgumentError: '0' is not a valid status
PR #13542 muted the error, but the issue remains. This commit fixes
the issue by allowing the enum value to be written directly via the
setter:
Issue.new.status = 0 # This now sets status to :open
Assigning a value directly via the setter like this is not part of the
documented public API, so users should not rely on this behavior.
Closes #13530.

Previously, the writer methods would simply check whether the passed
argument was the symbol representing the integer value of an enum field.
Therefore, it was not possible to specify the numeric value itself but
the dynamically defined scopes generate where clauses relying on this
kind of values so a chained call to a method like `find_or_initialize_by`
would trigger an `ArgumentError`.

The dynamic finder was creating the method signature with the parameters name,
which may have reserved words and this way creating invalid Ruby code.
Closes: #13261
Example:
# Before
Dog.find_by_alias('dog name')
# Was creating this method
def self.find_by_alias(alias, options = {})
# After
Dog.find_by_alias('dog name')
# Will create this method
def self.find_by_alias(_alias, options = {})

Currently `scope_chain` uses same array for building different
`scope_chain` for different associations. During processing
these arrays are sometimes mutated and because of in-place
mutation the changed `scope_chain` impacts other reflections.
Fix is to dup the value before adding to the `scope_chain`.
Fixes #3882.

PR #5210 added a Friendship model to illustrate a bug, but in doing so
created a confusing structure because both belongs_to declarations in
Friendship referred to the same side of the join. The new structure
maintains the integrity of the bug test while changing the follower
relationship to be more useful for other testing.

This caused a bug with the new associations implementation, because now
association conditions are represented as Arel nodes internally right up
to when the whole thing gets turned to SQL.
In Rails 3.2, association conditions get turned to raw SQL early on,
which prevents Relation#merge from interfering.
The current implementation was buggy when a default_scope existed on the
target model, since we would basically end up doing:
default_scope.merge(association_scope)
If default_scope contained a where(foo: 'a') and association_scope
contained a where(foo: 'b').where(foo: 'c') then the merger would see
that the same column is representated on both sides of the merge and
collapse the wheres to all but the last: where(foo: 'c')
Now, the RHS of the merge is left alone.
