postgresql - 创建 : could not connect to database template1: FATAL: password authentication failed for user

Question

通过 Homebrew 安装了 Postgresql。我想在解压缩“.tar”后创建一个新数据库。但是我有这个问题。

Michael-Adelekes-MacBook:wikiful madeleke13$ sudo su postgres -c 'createuser-P--superuser madeleke13'

bash: createuser-P--superuser: command not found

Michael-Adelekes-MacBook:wikiful madeleke13$ sudo su postgres -c 'createuser-P-superuser madeleke13'

bash: createuser-P-superuser: command not found

Michael-Adelekes-MacBook:wikiful madeleke13$ sudo su postgres -c 'createuser -P --superuser madelek13'

Password: Enter password for new role: Enter it again:

Michael-Adelekes-MacBook:wikiful madeleke13$ createdb -T template0

newdbPassword:
Password:

createdb: could not connect to database template1: FATAL: password authentication failed for user "madeleke13"

Michael-Adelekes-MacBook:wikiful madeleke13$

我不明白为什么我以前没有问题却无法验证我的用户名。

Answer 1

问题是此命令中的用户名:sudo su postgres -c 'createuser -P --superuser madelek13'

请注意用户名与用户帐户名不同:madeleke13。提供给 createuser 命令的用户名中缺少“e”，因此身份验证失败。
