Forgotten Passwords in PostgreSQL
Many PostgreSQL users ask about the USERNAME
and PASSWORD
for their database for the first time when logging in perhaps. However, just learning these settings isn’t all you need to know.
What is Server in Rails 4? It uses the PostgreSQL server with Ruby on Rails 4
.
Thus integrating the back-end with a front-end application that uses the ROR
framework, short for Ruby on Rails
.
Today we will be looking in-depth at the basic setup of your PostgreSQL and the default user configurations that precede it.
Initial Configuration and Setup of PostgreSQL
You’ll be hit with something like this the first time you run the PostgreSQL setup.
It asks you to provide a password for the SUPERUSER
called POSTGRES
. So when you open PGADMIN4
or the console version PSQL
, you’ll now want to log in using the username as POSTGRES
and the password as typed above.
How to log in using PGADMIN4
?
-
Boot up
PGADMIN4
. -
On the startup screen, you’ll be hit up with this.
-
Here, you will enter the password you used in the setup to log in.
If you forgot the password, you can go right ahead and click on
RESET MASTER PASSWORD
and follow the on-screen instructions.
Now we will learn how to log in using PSQL
.
-
Open
CMD
and run it with user privileges. -
In
CMD
, enter:C:\Users\User_Name > cd C:\Program Files\PostgreSQL\14\bin
Or as specified by your system. Instead of
14
, there may be a different version and a different directory to open thebin
folder. -
Now that you are inside the
directory
, typepsql.exe
.C:\Program Files\PostgreSQL\14\bin> psql -U postgres
The statement above tends to open the
psql
with theusername
aspostgres
, which is our defaultsuperuser
. -
This will lead you to:
Password for user postgres:
Here you will enter the same password you set in the setup
to log in and click Enter. You are now logged in.
the Superuser POSTGRES
in PostgreSQL
POSTGRES
is the initial SUPERUSER
of our database. It has all the known privileges to access and view an entire collection of database objects, views, and whatnot.
You can issue your SUPERUSERS
or just USERS
with limited access. A SUPERUSER
is the only entity that can issue CREATE
commands to add new users to the system.
Create Different USERS
in PostgreSQL
You can use the following statement to make a new SUPERUSER
with a unique name.
Create ROLE Wild_Cat WITH SUPERUSER
Or if you want to log in.
Create ROLE Wild_Cat Login
And then log in using psql
.
View USERS
and ALTER
Forgotten Passwords in PostgreSQL
If you have different USERS
, you can view them as follows.
select * from pg_user;
And then, from the list provided, such as in our example, we had the user WILD_CAT
, use the ALTER
statement to RESET
the password.
From here, we can then call the ALTER
statement as:
ALTER USER wild_cat WITH PASSWORD '[your_password]'
So today, we learned about the various ways we can define and use USERS
in PostgreSQL in SERVER IN RAILS 4
. We hope you continue learning and following our tutorials to better understand the concepts behind different solutions to a problem.
