1. Identify the source of the PostgreSQL 22009 error:The PostgreSQL 22009 error is caused by a syntax error in the SQL query. To identify the source of the error, you can use the following code snippet to check the query for any syntax errors:

SELECT * FROM pg_stat_activity WHERE state = '22009';

2. Fix the syntax error:Once the source of the error is identified, you can fix the syntax error by modifying the query accordingly. For example, if the query contains a missing comma, you can add the comma to the query to fix the syntax error.

3. Test the query:Once the syntax error is fixed, you can test the query to make sure it is working correctly. To do this, you can use the following code snippet to execute the query and check the results:

SELECT * FROM pg_stat_activity WHERE state = '22009';

4. Monitor the query: To ensure that the query is running correctly and to prevent future errors, it is important to monitor the query. This can be done by using an automated database observability tool, such as Datadog. This tool can be used to monitor the query and alert you if any errors occur. It can also be used to track the performance of the query and identify any potential issues. This can help you quickly identify and fix any errors that may occur in the future.
