'postgres' user not created when i install postgreSQL 12 with EnterpriseDB, in installation process there is step in the beginning where you create superuser 'postgres' and give him password, but it's don't creates
% sudo -u postgres psql
psql: error: could not connect to server: FATAL: password authentication failed for user "postgres"
It's not strange because i don't have user 'postgres' (that must be superuser), or any other users
I tried fix it and create user by my self, but how i understand manually adding user don't change anything
