当一个系统调用失败, 错误的符号值(例如, ENOMEM)和对应的字串(Out of memory) 都显示。strace 有很多命令行选项,其中最有用的是 -t 来显示每个调用执行的时间,-T 来显示调用中花费的时间,-e 来限制被跟踪调用的类型(例如strace –eread,write ls表示只监控read和write调用),以及-o 来重定向输出到一个...
不允许压缩和线外(out-of-line,有的也叫行外)存储。对于那些不能TOAST机制的数据类型,默认都是该策略,比如整数类型(INT,SMALLINT,BIGINT)、字符类型(CHAR)、布尔类型(BOOLEAN)等等。(2) EXTENDED允许线外存储和压缩。这是大多数可以使用TOAST机制的数据类型默认存储策略。它首先尝试压缩,如果这仍不能将数据放入...
