How to solve psql: error: failed to connect to server 'localhost' (::1)?

Question

PostgreSQL

Good afternoon, I installed PostgreSQL, but an error occurs during authorization:

C:\Users\Admin>psql v-
Пароль пользователя Егор:
psql: ошибка: подключиться к серверу "localhost" (::1), порту 5432 не удалось: ВАЖНО:  пользователь "Егор" не прошёл проверку подлинности (по паролю)

Immediately, an important detail, earlier the Windows account was called Egor, now Admin, and more importantly, I did not replace all the matches in the registry, since there are a million of them, but I installed PostgreSQL after renaming.
Reinstalled 2 times, password 100% correct. I also tried to change the user on the advice, but it did not help either.


Can you please tell me what else to try?

Answer 1

If a freshly installed postgres, try psql -U postgres, because the installer does not create an account with your name in postgres itself
