SessionStore was recently changed to delegate to hash
object instead of inherit from it. Since we don't want
to extend SessionStore with every method implemented in
Hash, it's better to just convert any object passed to
debug_hash (which is also better as we don't require
to pass Hash instance there, it can be any object that
can be converted to Hash).

postgresql adapter should quote not a number and infinity correctly for float columns

Beginning and end of hour support for Time and DateTime

Use Hash#fetch instead of has_key? check

Enable misnamed time_with_timezone_tests in activesupport core_ext

Force given path to http methods in mapper to skip canonical action checking

Update documentation for button_to.

This fixes the following scenario:

    resources :contacts do
      post 'new', action: 'new', on: :collection, as: :new
    end

Where the /new path is not generated because it's considered a canonical
action, part of the normal resource actions:

    new_contacts POST   /contacts(.:format)          contacts#new

Fixes #2999
