You can use the psql command-line tool to connect to the running PostgreSQL database and view the current username, password, and database name.
Here's how to do it:
Connect to the running PostgreSQL container using podman exec command. Replace postgres-container with the name of your PostgreSQL container.
Once connected, run the following command to view the current username:
To view the current database name, run:
To view the current user's encrypted password, run:
```
passwd FROM pg_shadow WHERE usename = 'username';
```
Replace username with the current username.
Note that the password is encrypted and cannot be directly read. To verify a password, you would need to hash the provided password and compare it with the hashed password stored in the pg_shadow table.
It is not recommended to rely on the pg_shadow table to manage user accounts and passwords, as it is a system table and not meant for direct user interaction. Instead, you should use the CREATE USER and ALTER USER commands to create and manage user accounts, and the CREATE DATABASE command to create databases.
