This commit fixes an issue where pluck columns were not correctly casting types when using PostgreSQL. The changes include modifications to the calculations_test.rb file in the ActiveRecord test cases. Specifically, the commit adds assertions to test the pluck method's ability to correctly cast types for columns like approved, last_read, and written_on. Additionally, the commit includes a new assertion to test the pluck method's ability to handle conflicting column names by using the min function for written_on and replies_count columns.

Overall, this commit addresses a bug related to type casting in the pluck method when using PostgreSQL. By adding new assertions and modifying existing ones in the calculations_test.rb file, the commit ensures that pluck columns now correctly cast types for various columns, including handling conflicting column names.

In this commit, the minimum value in a test case is now being picked based on certain conditions. The changes were made in the calculations_test.rb file in the activerecord/test/cases directory. The specific changes include modifying the pluck method to now select the minimum value of certain attributes for a given topic. This change ensures that the minimum value is correctly selected based on the specific conditions provided in the test case.

Overall, this commit enhances the functionality of the pluck method in calculating the minimum value for specific attributes in a given topic. By making these adjustments, the test case now accurately selects the minimum value based on the conditions specified, improving the overall accuracy and reliability of the testing process.

In this commit, the code in the insert_all_test.rb file has been modified to add an ensure block that resets the table name to "books" after a test is run. This change ensures that the table name is properly reset after the test is completed, preventing any potential issues with the table name being incorrectly set for subsequent tests. The commit includes one addition and no deletions, with the specific change being made to the test_insert_all_when_table_name_contains_database method.

Overall, this commit improves the reliability and consistency of the tests by ensuring that the table name is reset to its original state after each test is run. This helps to maintain the integrity of the test environment and prevents any unintended side effects from lingering changes to the table name. The addition of the ensure block provides a safeguard to ensure that the table name is always properly reset, enhancing the overall quality of the testing process.

• activerecord/test/cases/insert_all_test.rb

This commit addresses an issue where a syntax error would occur when the table_name contains the database name. By parameterizing the table_name when constructing the insert alias, the code is now able to handle this scenario without causing any errors. This change ensures that the database name within the table_name is properly handled and does not disrupt the functionality of the code.

Overall, this update improves the robustness and reliability of the code by addressing a potential source of syntax errors. By parameterizing the table_name, the code is now able to handle a wider range of scenarios without encountering issues related to the database name being included within the table_name. This change enhances the overall stability and performance of the code when working with table names that contain the database name.
