I downloaded PostgreSQL version 10, pgadmin4 was installed on my computer with it, but when I try to open it, the download starts first, then an error pops up: how to solve this problem and run pgadmin? Also, using the command line psql I am asked to enter a password. When I enter the password that I specified during the postgresql installation, I get an incorrect password error. You do not know what this program wants from me, what password should I enter? Thanks in advance for any help
