postgresql psql 命令 \d 沒有列出索引

[英]postgresql psql command \d does not list indexes

我使用以下命令在 PGSQL(版本 13)中創建了一個表:

db1=# create table temp2(
foo int PRIMARY KEY,
bar varchar(20) UNIQUE NOT NULL
);
CREATE TABLE

\dd+命令不列出表的關聯索引(與我從閱讀各種站點收集到的相反。)

db1=# \d temp2
 foo    | integer               |           | not null |
 bar    | character varying(20) |           | not null |

db1=# \d+ temp2
 foo    | integer               |           | not null |         | plain    |              |
 bar    | character varying(20) |           | not null |         | extended |              |

有沒有辦法獲取與表關聯的列表索引?

謝謝你,艾哈邁德。

您將tuples_only設置為on

 create table temp2(
foo int PRIMARY KEY,
bar varchar(20) UNIQUE NOT NULL
);

test(5432)=# \d temp2
                      Table "public.temp2"
 Column |         Type          | Collation | Nullable | Default 
--------+-----------------------+-----------+----------+---------
 foo    | integer               |           | not null | 
 bar    | character varying(20) |           | not null | 
Indexes:
    "temp2_pkey" PRIMARY KEY, btree (foo)
    "temp2_bar_key" UNIQUE CONSTRAINT, btree (bar)

test(5432)=# \pset tuples_only on


test(5432)=# \d temp2
 foo    | integer               |           | not null | 
 bar    | character varying(20) |           | not null | 

test(5432)=# \pset tuples_only off
test(5432)=# \d temp2
                      Table "public.temp2"
 Column |         Type          | Collation | Nullable | Default 
--------+-----------------------+-----------+----------+---------
 foo    | integer               |           | not null | 
 bar    | character varying(20) |           | not null | 
Indexes:
    "temp2_pkey" PRIMARY KEY, btree (foo)
    "temp2_bar_key" UNIQUE CONSTRAINT, btree (bar)

通過執行以下操作進行驗證:

\pset
border                   1
columns                  0
csv_fieldsep             ','
expanded                 off
fieldsep                 '|'
fieldsep_zero            off
footer                   on
format                   aligned
linestyle                ascii
null                     'NULL'
numericlocale            off
pager                    1
pager_min_lines          0
recordsep                '\n'
recordsep_zero           off
tableattr                
title                    
tuples_only              on
unicode_border_linestyle single
unicode_column_linestyle single
unicode_header_linestyle single


您需要 \di 來獲取索引信息。 查看手冊

字母E、i、m、s、t、v分別代表外部表、索引、物化視圖、序列、表和視圖。
