When encountering ` from PostgresDB, the user should:
- Understand the Context: Recognize that this message is associated with stored procedures that can return more result sets than were declared. It's an informational message, not an error.
- Review the Procedure: Look at the stored procedure related to the operation. Check if the procedure is designed to return multiple result sets and if this behavior is expected.
- Analyze Application Logic: Consider how your application handles multiple result sets. Ensure your application logic is prepared to handle or iterate through multiple result sets if necessary.
- Monitor Performance: If unexpected, multiple result sets could impact performance. Utilize monitoring tools or queries to check the performance. For instance, monitoring queries like
EXPLAIN ANALYZE
with your procedure call can help understand its execution plan and performance. - Adjust Procedure if Necessary: If the multiple result sets are unintended, modify the stored procedure to return the expected number of result sets. This might involve adjusting the logic within your procedure or revising the queries being executed within.
- Consult Documentation/Community: Since there's no database administrator, refer to PostgreSQL documentation or trusted community forums for guidance on handling dynamic result sets and optimizing stored procedures.
- Run Diagnostic Queries (if necessary): For further investigation, you can run diagnostic queries to understand more about your database's behavior. Examples include:
SELECT * FROM pg_stat_activity;
to view current database activities.EXPLAIN <your_procedure_call>;
to see the execution plan of your procedure.
Remember, handling dynamic result sets properly requires understanding of both your application's requirements and how PostgreSQL functions. Adjustments should be made with care to avoid unintended consequences.
