Question

I have installed PostgreSQL 8.4, Postgres client and Pgadmin 3. Authentication failed for user \"postgres\" for both console client and Pgadmin. I have typed user as \"postg

Answer 1

This happens due to caching.

When you run, php artisan config:cache, it will cache the configuration files. Whenever things get change, you need to keep running it to update the cache files. But, it won't cache if you never run that command.

This is OK for production, since config don't change that often. But during staging or dev, you can just disable caching by clearing the cache and don't run the cache command

So, just run php artisan config:clear, and don't run the command previously to avoid caching.

Time flies!

On version 12, I have to use "password" instead of "ident" here:

local   all             postgres                                password

Connect without using the -h option.

Answer 3

As a rule of thumb: YOU SHOULD NEVER EVER SET A PASSWORD FOR THE POSTGRES USER.

If you need a superuser access from pgAdmin, make another superuser. That way, if the credentials for that superuser is compromised, you can always ssh into the actual database host and manually delete the superuser using

sudo -u postgres -c "DROP ROLE superuser;"

Answer 4

Once you are in your postgres shell, Enter this command

postgres=# \password postgres

After entering this command you will be prompted to set your password , just set the password and then try.

Answer 5

In my case, its Password was longer than 100 characters. Setting it to a smaller character password worked.

Actually I am wondering is there a reference somewhere to that.
