lookup_cmd() - поиск по списку cmdlist
execute_command()
command_handler()

при обработке команд call и print вызывается функция print_command_1() из нее вызывается value_print(), а из нее - apply_ext_lang_val_pretty_printer() и c_value_print_inner()

Для тестирования 

b exec_simple_query
print *parsetree_list 
b ExecProcNode
p node->ps->plan

———- еще вариант, но он не работает с IDE
