1. Identify the source of the error: PostgreSQL 22P02 is an error code that indicates a syntax error in the SQL query. To identify the exact source of the error, it is important to review the query and look for any syntax errors.

2. Fix the syntax error: Once the source of the error is identified, the syntax error can be fixed by making the necessary changes to the query. For example, if the query is missing a closing parenthesis, the query can be fixed by adding the missing parenthesis.

3. Test the query: After the syntax error is fixed, it is important to test the query to make sure that it is working correctly. This can be done by running the query in a PostgreSQL client and verifying that the results are as expected.

4. Monitor the query: To ensure that the query is running correctly and that any future errors are identified quickly, it is important to monitor the query. This can be done by using an automated database observability tool, such as Datadog, which can monitor the query and alert the user if any errors occur.

5. Use an automated database observability tool: To ensure that any future errors are identified quickly and that the query is running correctly, it is recommended to use an automated database observability tool. This tool can monitor the query and alert the user if any errors occur, allowing for quick resolution of any issues.
