Because if post has 100k + records and all these 100k records would be loaded in memory + even though the comment id was supplied. + + Fix is to use in-memory records only if loaded? is true. Otherwise + load the records using full sql. + + Fixes #10509. + + *Neeraj Singh* + +* `inspect` on Active Record model classes does not initiate a + new connection. This means that calling `inspect`, when the + database is missing, will no longer raise an exception. + Fixes #10936. + + Example: + + Author.inspect # => "Author(no database connection)" + + *Yves Senn* + +* Handle single quotes in PostgreSQL default column values. + Fixes #10881. + + *Dylan Markow* + +* Log the sql that is actually sent to the database. + + If I have a query that produces sql + `WHERE "users"."name" = 'a b'` then in the log all the + whitespace is being squeezed. So the sql that is printed in the + log is `WHERE "users"."name" = 'a b'`. + + Do not squeeze whitespace out of sql queries. Fixes #10982. + + *Neeraj Singh* + +* Fixture setup does no longer depend on `ActiveRecord::Base.configurations`. + This is relevant when `ENV["DATABASE_URL"]` is used in place of a `database.yml`. + + *Yves Senn* + +* Fix mysql2 adapter raises the correct exception when executing a query on a + closed connection. + + *Yves Senn* + * Ambiguous reflections are on :through relationships are no longer supported.
