I want to create a new database, and when I try to create it, it asks me for the password for the username, but I don’t remember it and don’t know how to create a new username. Additionally, when I go to the shell and reach the point where I need to type the password, I find that I cannot type in the shell. I don’t know the reason.

I tried going to pgAdmin and looking for a solution in the help section but didn’t find one. I searched the internet for solutions, and one of them suggested I write the following in CMD: psql -U myuser, but I get a message (the phrase is in the image) and I cannot type anything due to the psql issue when prompted for the password.enter image description here

Can you help me? Thank you in advance
