To fix the “40003 – statement_completion_unknown” error, follow these steps:
1. Check the SQL statement: Start by reviewing the SQL statement that triggered the error. Look for any syntax errors, missing or incorrect parameters, or any other issues that could cause the completion failure. Ensure that the statement is properly formatted and follows the PostgreSQL syntax rules.
2. Verify the database connection: Ensure that you have a stable and valid connection to the PostgreSQL database. Check the connection parameters, such as the host, port, username, and password, to ensure they are correct. If necessary, reconnect to the database to establish a fresh connection.

Analyze the logs to identify any patterns or specific queries that consistently trigger the “40003 – statement_completion_unknown” error.
