Question

当我有一个非常宽的列（如json文档）并且我使用扩展显示使内容至少部分可读时，我仍然看到非常难看的记录分隔符，它似乎想要像最宽的栏目，如下：

有没有办法避开“破碎之海”？

- [记录1] - + --------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ------------------------------------------ -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------

要避免破折号，请使用\pset format unaligned，例如：

t=# \x
Expanded display is on.
t=# \pset format unaligned
Output format is unaligned.
t=# with ts as (select generate_series('2010-01-01'::timestamp,'2010-01-10'::timestamp,'1 day'::interval) s) select array_agg(s) from ts;                 array_agg|{"2010-01-01 00:00:00","2010-01-02 00:00:00","2010-01-03 00:00:00","2010-01-04 00:00:00","2010-01-05 00:00:00","2010-01-06 00:00:00","2010-01-07 00:00:00","2010-01-08 00:00:00","2010-01-09 00:00:00","2010-01-10 00:00:00"}

正如你所看到的，没有破折号，但是长长的字符串仍然被窗口的长度包裹在线上（或者根本没有被包裹）。在没有格式化的字符串的情况下，这是解决方案，但是你提到了json - 它可以以一种漂亮的方式划分。要这样做而不是在psql中使用未对齐格式，请使用jsonb_pretty函数或其他函数的pretty标志，例如（使用array_to_json(..., true)：

t=# with ts as (select generate_series('2010-01-01'::timestamp,'2010-01-31'::timestamp,'1 day'::interval) s) select array_to_json(array_agg(s),true) from ts;
array_to_json|["2010-01-01T00:00:00",
 "2010-01-02T00:00:00",
 "2010-01-03T00:00:00",
 "2010-01-04T00:00:00",

注意我仍然使用未对齐的格式来避免＆＃34; +＆＃34;虽然...
