1. Identify the root cause of the PostgreSQL 57P01 error:This error is usually caused by a syntax error in the SQL query. To identify the root cause, you can use the following code snippet to view the query that caused the error:

SELECT query FROM pg_stat_activity WHERE state = '57P01';

2. Fix the syntax error in the query: Once you have identified the query that caused the error, you can fix the syntax error by editing the query. 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 you have fixed the syntax error, you can test the query to make sure it works correctly. You can use the following code snippet to test the query:

SELECT * FROM pg_stat_activity WHERE state = '57P01;

4. Monitor the database for future errors: To prevent future PostgreSQL 57P01 errors, it is recommended to use an automated database observability tool. This tool can monitor the database for any errors and alert you when an error occurs. This will help you quickly identify and fix any errors before they cause any major issues.
