Hmm, you raise a good point. Isn't this a fundamental problem with prepared statements? If there is DDL on the relations of the prepared statement query, shouldn't the prepared statement be considered invalid at that point and raise an error to the user?
Although the main point of a prepared statement is to avoid repeated parse analysis and planning of the statement, PostgreSQL will force re-analysis and re-planning of the statement before using it whenever database objects used in the statement have undergone definitional (DDL) changes or their planner statistics have been updated since the previous use of the prepared statement.
