[#2774 state:committed]

Some databases (e.g. Oracle) does not allow "AS" between table name and table alias name, for others it is optional

quoted_date converts time-like objects to ActiveRecord::Base.default_timezone before serialization. This allows you to use Time.now in find conditions and have it correctly be serialized as the current time in UTC when default_timezone == :utc [#2946 state:resolved]

Revert "Revert "Generate proper :counter_sql from :finder_sql when there is a newline character immediately following 'SELECT' [#2118 state:resolved]""

This reverts commit 80f1f863.

The feature doesn't work on Postgres, so don't test it on Postgres.
Also, Postgres compatibility is irrelevant to the ticket/patch in question.

Revert "Generate proper :counter_sql from :finder_sql when there is a newline character immediately following 'SELECT' [#2118 state:resolved]"

This reverts commit 4851ca9e.

Changed ActiveRecord::Base#exists? to invoke find_initial so that it is compatible with, and doesn't lose, :include scopes (references to eager loaded tables)

Fixed issue where block is not called on the very first invocation of a find_or_create_by_ automatic finder.
[#1224 state:committed]

Dynamic finders should use the ActiveRecord::Base::find method instead of ::find_initial, :find_last, and ::find_all.

This is so when people override ActiveRecord::Base::find, the new ::find method will also be invoked by the dynamic finders.
Associations for instance do go through ::find, so this makes it more consistent.
Also removed the unnecessary deprecation silence blocks.
