【问题描述】:
我正在尝试更改我正在运行的 PostgreSQL 数据库的 client_encoding 配置变量的默认值。我希望它是UTF8,但目前它被设置为LATIN1。
数据库已设置为使用 UTF8 编码:
application_database=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
----------------------+----------+----------+-------------+-------------+--------------------------------------
postgres | postgres | LATIN1 | en_US | en_US |
application_database | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | postgres=CTc/postgres +
| | | | | application_database=Tc/postgres
template0 | postgres | LATIN1 | en_US | en_US | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | LATIN1 | en_US | en_US | =c/postgres +
| | | | | postgres=CTc/postgres
(4 rows)
哪个according to the docs应该已经导致客户端使用UTF8作为其默认client_encoding(强调我的):
client_encoding (string)设置客户端编码(字符集)。 默认使用数据库编码。
但它没有:
$ sudo psql --dbname=application_database
psql (9.1.19)
Type "help" for help.
application_database=# SHOW client_encoding;
client_encoding
-----------------
LATIN1
(1 row)
我什至尝试使用ALTER USER <user> SET ... 更改我登录用户的默认配置:
application_database=# ALTER USER root SET client_encoding='UTF8';
ALTER ROLE
application_database=# SELECT usename, useconfig FROM pg_shadow;
usename | useconfig
----------------------+------------------------
postgres |
root | {client_encoding=UTF8}
application_database |
(3 rows)
但这也没有效果:
$ sudo psql --dbname=application_database
psql (9.1.19)
Type "help" for help.
application_database=# SELECT current_user;
current_user
--------------
root
(1 row)
application_database=# SHOW client_encoding;
client_encoding
-----------------
LATIN1
(1 row)
我系统上的任何 PSQL 文件中都没有任何内容:
vagrant@app-database:~$ cat ~/.psqlrc
cat: /home/vagrant/.psqlrc: No such file or directory
vagrant@app-database:~$ cat /etc/psqlrc
cat: /etc/psqlrc: No such file or directory
vagrant@app-database:~$ sudo su
root@app-database:/home/vagrant# cat ~/.psqlrc
cat: /root/.psqlrc: No such file or directory
我正在运行 PosgreSQL 9.1:
application_database=# SELECT version();
version
-------------------------------------------------------------------------------------------------------------
PostgreSQL 9.1.19 on x86_64-unknown-linux-gnu, compiled by gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3, 64-bit
(1 row)
