   "Prepared statements only last for the duration of the current database
session. When the session ends, the prepared statement is forgotten, so it
must be recreated before being used again. This also means that a single
prepared statement cannot be used by multiple simultaneous database
clients; however, each client can create their own prepared statement to
use."
