As Ron already pointed out, these are different things. PostgreSQL is a
Database. PgAdmin ist a Client for that database. You can't use one
instead of the other. You can only use them together (but of course you
could use a different client instead of PgAdmin4).

That looks fine except that the user "basic_user" doesn't exist. You
should create that before restoring the backup. Or could fix the errors
after the fact but for that you need to understand what went wrong.
