Summary of Changes

Hello @rahim-kanji, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the robustness of the verify_server_variables function by replacing a critical assert statement with a proxy_warning. This modification prevents the application from crashing when an expected server variable value does not match the actual status, which can occur in specific edge cases such as COPY FROM STDIN failures where internal libpq state might not be consistently updated. Instead of an abrupt termination, the system will now log a detailed warning, allowing for continued operation while still notifying administrators of potential discrepancies.

Highlights

• Error Handling Improvement: The assert statement in verify_server_variables() has been replaced with a proxy_warning.
• Increased Robustness: This change prevents application crashes due to server variable mismatches, particularly in edge cases like COPY FROM STDIN failures where internal libpq state might not be updated.
• Detailed Logging: A detailed warning message is now logged, including the server variable name, its current status value, and the expected value, providing better diagnostic information without halting execution.

Code Review

This pull request correctly replaces a strict assert with a proxy_warning in verify_server_variables for debug builds, preventing unnecessary crashes on non-buggy edge cases. The change is well-justified and improves the debugging experience. I've added one comment regarding mixed indentation, which should be addressed for code consistency.
