How are you connecting?:

1) No hostname

2) With hostname

Have you used the Postgres command line client 
psql(https://www.postgresql.org/docs/current/app-psql.html)?

In meantime find the pg_hba.conf file for the server and post the 
contents starting at the line:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

here. Do this only if you are alright with sharing that information.

No you don't need to start over.

I have a very stupid password question. I don’t know whether a postgres database on my Mac has a pass word or not.

 

I access the database via the Aqua Data Studio frontend as the user postgres. I don’t think I ever added a password, and on the authentication panel the password box is empty but the Remember Password box is checked.

 

However on the user panel there is a sequence of black dots for the Password and Password confirmation. This suggests that I did set a password, but I don’t remember what it is.

 

How can I undo the damage? Is there some super user way in which I can undo the current password and set a new one. The database itself has several hundred tables, and I need to find a way to fix my stupid error.

 

I have a dump of the database.  I don’t know whether that is subject to the password or not. If it isn’t, I suppose I could start over from scratch.

If the database is on your Mac, then edit the pg_hba.conf file, and restart.

local   all             postgres         trust

That should give user "postgres" access with or without a password.
