您需要重新加载数据库,然后再次设置用户的密码(可能使用超级用户帐户),以便用户再次拥有MD5散列密码。

The password will be transmitted to the server in cleartext, and it might also be logged in the client's command history or the server log. psql contains a command \password that can be used to change a role's password without exposing the cleartext password. Note: ALTER USER is an alias...

i am using pgcrypto extension for password encryption in my PostgreSQL db. i am using same key to encrypt all passwords. When i use same key in different passwords(different strings) it gives same output. Samples: db=# select crypt('Sharon_1','alpha'); crypt --- aljp4LCkDT1k. (1 r...
postgres=# set password_encryption TO ON; SET Due to the same reason, the above statement was effectively the same as: PgSQL 1 2 postgres=# set password_encryption TO MD5; SET We could even use “true”, “1”,”yes” instead of “on” as an equivalent value. But now we have mult...
PostgreSQL 支持用户密码的加密存储(加密方式由password_encryption参数决定),确保数据库管理员无法得到用户的密码。 如果我们采用了 SCRAM 或者 MD5 加密的客户端认证,明文密码甚至不会在服务器中出现,因为客户端在发送之前就已经进行了密码加密。推荐使用 SCRAM 加密,因为它是一个互联网标准,而且比 PostgreSQL 使用的 ...
