Unable to connect to Postgres - role 'postgres' doesn't exist

[realtebo]

I downloaded binaries for PG 13 and decompress under bin\postgres\postgres...version...

I restarted Laragon and postgres started well.

Now I'm on pgadmin and I cannot connect to postgres.

I'm trying to use postgres as username but it says me that postgres role doesn't exists.

What's the trick?

I alkso tried from command line (it's my first time with Postgresql since a lot of years)

It looks for a db named 'mirko' ... I don't know why it's looking a db with my personal name as db name ... where does is this setup?

i still canot understand defaults ...

But using mirko as username works from pgadmin

Still I cannot login from command line

I will delete pgsql instllation dir and data and restart .

Is there anofficial guide to first run of pg under laragon?
