- Verify the SQL statement: Ensure that the SQL statement being executed is correct and does not contain any syntax errors. You can do this by running a syntax check on the query.
- Check for the existence of the prepared statement: If your application is trying to execute a prepared statement, ensure that the statement has been created before it is executed. Use the following query to check existing prepared statements:
SELECT * FROM pg_prepared_statements WHERE name = 'your_statement_name';
- Re-prepare the statement: If the prepared statement does not exist or has been invalidated (e.g., due to a database restart), you will need to re-prepare the statement before executing it again.
- Examine server logs: Look into the PostgreSQL server logs for any additional information regarding the error. This can provide clues on why the statement name is invalid. The location of these logs depends on your PostgreSQL configuration, but they can often be found in
/var/log/postgresql/ on Linux systems. - Check for transaction block issues: Ensure that the error is not being caused by an issue with transaction blocks, especially if using
SAVEPOINT and ROLLBACK TO SAVEPOINT. Ensure that the transaction block is properly initiated and that the savepoint names are correctly managed.
Remember, these actions are intended for immediate troubleshooting and may require further investigation depending on the outcomes.
