bool pg_send_execute ( resource $connection , string $stmtname , array $params )
Sends a request to execute a prepared statement with given parameters, without waiting for the result(s). This is similar to pg_send_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. The function's parameters are handled identically to pg_execute(). Like pg_execute(), it will not work on pre-7.4 versions of PostgreSQL.
Returns TRUE on success, FALSE on failure. Use pg_get_result() to determine the query result.
