What is PostgresDB 39001: Invalid SQLSTATE Returned

Check the PostgreSQL server log files for more detailed error messages surrounding the occurrence of error 39001. Use the command:tail -f /var/log/postgresql/postgresql-<version>-main.logReplace <version> with your PostgreSQL server version.Verify that all functions called in the SQL statement are correctly defined and available in the database. Use the command:SELECT proname FROM pg_proc WHERE proname = 'your_function_name';Replace your_function_name with the name of the function involved in the error.Ensure that the SQLSTATE being referred to or returned by any custom functions or triggers is correctly formatted and valid. PostgreSQL expects a five-character string as SQLSTATE.If using a PL/pgSQL block or a custom function that raises exceptions or uses SQLSTATE, verify the SQLSTATE used is correct. Example check:DO $$BEGIN RAISE EXCEPTION USING SQLSTATE = 'XXXXX';EXCEPTION WHEN OTHERS THEN RAISE NOTICE 'Invalid SQLSTATE detected';END$$;Replace XXXXX with the SQLSTATE being used.Check for any recent changes in database schemas, functions, or triggers that might not have been correctly applied or could be causing this error.If possible, reduce the complexity of the query or function that is causing the error, to isolate the specific condition or command causing the issue.Review the PostgreSQL documentation for any known issues or limitations related to SQLSTATE values and their usage in your version of PostgreSQL.
