Cloud SQL Postgres 中的密码重置问题

Question

I am getting below error intermittently in my Cloud SQL instance,

UTC [2647634]: [1-1] db=postgres,user=postgres FATAL:  password authentication failed for user "postgres""

After rest the password back, the process is working as usual. Don't know which process is resetting the password. I checked the log and cant find any password resetting related log, before this issue occurred.

Answer 1

Unless log_statement is set to ddl or above, password resets would not be logged.

I would worry that you have been hacked. There are few innocent reasons for your password to change without you changing it.
