When encountering <Cell R19C1 '01P01: Deprecated Feature'>
from PostgresDB, the recommended actions for a user are as follows:
- Identify Deprecated Feature: Determine which feature or function in your SQL query or database schema is deprecated by consulting the PostgreSQL documentation for the version you are using. PostgreSQL documentation lists deprecated features and their alternatives.
- Review Code and Queries: Review your SQL code, functions, and stored procedures to identify usage of the deprecated feature. You can search your codebase for the deprecated feature's name.
- Run Investigation Queries: If applicable, run SQL queries to help identify deprecated features in use. For example, to find functions or procedures that might be using deprecated features, you can query system catalogs:
SELECT proname, prosrc FROM pg_proc WHERE prosrc ILIKE '%deprecated_feature_name%';
- Replace
deprecated_feature_name
with the name or part of the name of the deprecated feature. - Check Application Logs: Review application logs for any warnings or errors related to the deprecated feature. PostgreSQL often logs warnings about the use of deprecated features.
- Consult Documentation for Alternatives: Once you have identified the deprecated feature, consult the PostgreSQL documentation for recommended alternatives. The documentation will often suggest the new feature or approach that should be used instead.
- Update Code: Update your SQL queries, stored procedures, and any application code to use the recommended alternatives. Make sure to thoroughly test your changes to ensure they work as expected without breaking existing functionality.
- Monitor After Changes: After updating your code, monitor your application and database performance to ensure that the changes have not introduced any new issues.
- Stay Informed on Updates: Regularly review PostgreSQL release notes and documentation to stay informed about new deprecations and recommended practices. This proactive approach can help prevent future issues related to deprecated features.
