I recently created a test database but I would like it to be accessible to all users.
I created the database as user postgres then use the command
GRANT ALL ON DATABASE dbname TO public;
But when I log out and try to connect to it with a different user I get this error
psql -d dbname
psql: FATAL: role "username" does not exist
I don't want to have to create a user for each person who will be accessing the database which is the reason i wanted to make it public. Is there a permission that I am still missing?
