This commit adds a Date decoder to the pg adapter in order to type cast dates at the connection level. This means that columns of type date will now be type cast to ruby Date when running a raw query through ActiveRecord::Base.connection.select_all. This fix addresses issue #51448 and ensures that date columns are properly converted to the appropriate data type in Ruby.

Overall, this commit enhances the functionality of the pg adapter by improving the handling of dates and ensuring that they are correctly type casted when interacting with the database through ActiveRecord. This change helps to maintain data integrity and consistency when working with dates in Ruby applications.

This commit adds a missing ostruct require statement to the http_token_authentication_test.rb file. The ostruct library is needed for certain functionalities within the test file, and its absence was causing errors during testing. By including the require statement, the code now has access to the necessary ostruct functionality, allowing the tests to run smoothly without any issues.

Overall, this commit addresses a small but crucial oversight in the test file, ensuring that the ostruct library is properly loaded and available for use. This improvement enhances the reliability and effectiveness of the tests, contributing to a more robust testing environment for the codebase.

This commit in Arel makes Or nodes "Nary" like And, which reduces the depth of the tree for large OR conditions. The fix addresses an issue reported on GitHub that significantly decreases the depth of the tree, making it more efficient. Initially hesitant about the fix, the developer ultimately decided to implement it since And nodes are already structured in a similar way.

Interestingly, after implementing the fix, the reported repro script now causes SQLite to fail with the error message "SQLite3::SQLException: Expression tree is too large (maximum depth 1000)." This change improves the efficiency of large OR conditions in Arel and aligns the structure of Or nodes with And nodes.
