Troubleshooting complex post queries can be challenging, especially when dealing with custom post types or intricate query conditions. This snippet provides a debugging tool that logs the SQL query for any post retrieval to help identify and resolve issues.

The posts_request filter is utilized to capture the SQL query string just before it is sent to the database. The query is then logged to a debug file or displayed on the screen for developers to analyze.

This tool is invaluable for optimizing queries, understanding how different parameters affect the SQL generated, and ensuring that queries are as efficient as possible.

The snippet includes security considerations to ensure that sensitive information is not exposed in production environments, along with tips on how to integrate this tool seamlessly into existing development workflows.

Further extensions of this debugging tool are discussed, such as integrating with other debugging plugins or tools, and how to use it during automated testing processes.
