How to connect to PostgreSQL database using pgAdmin 4?

 How to connect to PostgreSQL database using pgAdmin 4? In order to set up a connection to the PostgreSQL database, run pgAdmin 4, for example, from the Start menu. As a result, pgAdmin 4 will start. Then click the menu "Object->Create->Server" or right-click on the item "Servers" and select "Create->Server". The server connection settings window will open. On the General tab, we invent and enter the name of our server in the Name field. On the Connection tab, enter the server IP address, username, password, and if you want, you can check the “Save password?” to save the password and not to enter it every time you connect. If the standard port (5432) of the PostgreSQL server has been changed, then you also need to change it here. Press the "Save" button. Note! The PostgreSQL server must be installed, configured and running. We considered an example of installing and configuring PostgreSQL DBMS on Linux Debian in the material “Installing ...

Benefits of PoS

 Benefits of PoS

The main advantage for users is that they do not need to use powerful computer equipment. Coin mining can be carried out on ordinary personal computers.

The main advantage results in low electricity costs, which has been a major problem with PoW mining. Users do not need to install additional boards, coolers, voltage stabilizers and other types of equipment that contribute to the stable operation of powerful equipment. It is enough for modern forgers to have a powerful laptop or personal computer, as well as constant access to the Internet.

Cryptocurrency is protected from inflation. Due to the known number of coins that are on the market, there is no need to create new coins, which would lead to a depreciation. Fluctuations are possible only due to dynamic changes in the situation on the exchange, which reduces the number of factors that negatively affect the rate of coins.

Here is the minimum amount of empty cryptocurrency that does not have a significant justification. This provision indirectly affects the cost of energy carriers, stabilizing this indicator.

Users have a high level of involvement in the cryptocurrency mining process. For efficient mining, users need to buy a large number of coins. Having large assets, the investor becomes interested in the development and stability of the project. Members of the cryptocurrency community always support it when launching a new coin. In theory, the miner can easily switch from one type of coin to another if he notices that the project is unprofitable. In practice, this will take a certain amount of time, which reduces the efficiency of this process. Also, when transferring funds, the conversion will entail some losses, so it often becomes unprofitable to switch.

This is a promising algorithm that may become the main one in the future if mining using other algorithms becomes impossible. An increase in the power of mining equipment will lead to the fact that all coins will be mined even in the most popular chains, despite their complexity. In this case, transactions can only be carried out via PoS.
