1) Requires password all the time when starting pgAdmin 4 (which is irrelevant for localhost)
Solution:
go to C:\Program Files\PostgreSQL\15\pgAdmin 4\web\
make a copy of the file config.py
call it config_local.py
Change MASTER_PASSWORD_REQUIRED to False
2) By setting the bin folder to PATH, you can call from the terminal
psql
but get error: psql: error: connection to server at “localhost” (::1), port 5432 failed: FATAL: password authentication failed for user “vasya”
Solution:
run from regular user psql -U postgres
