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!

How to buy a rod with the right action, power and strength? In the store, it is impossible to find out exactly how close its bending curve is to the ideal. What should you pay attention to first of all? Today, store shelves are filled with rods of many companies.
When buying a rod, you should pay attention to the authority of the dealer. Don't buy rods from random people. If you buy a company's products, try to find out about its reputation. There are manufacturers who have been working in this industry for tens and hundreds of years and have impeccable authority.
You should familiarize yourself with the inscriptions that are on the rod. Usually its length, class, casting weight or test are indicated there. The casting weight is the maximum allowable weight of an artificial bait that can be handled when using this rod to build a spinning or long casting rod.
The weight of the rod is very important. These data are usually absent on rods. They should be found out from the documents accompanying the goods.
High quality rods equipped with guides usually have an inscription indicating the type of guide.
After reading all the stickers, you need to:
1. Carefully inspect the rod; identify the absence of cracks, burrs, asymmetries and curvature.
2. Taking the butt part or the handle, wave the rod first in the vertical and horizontal plane, and then “draw” circles in the air with its end. The rod should bend equally in all directions. Squeaks and rattles are unacceptable. Slightly swing the rod as if casting a fishing rod and stop the movement in a position parallel to the floor surface. If he did not freeze in a horizontal position, but, having bent, touched the floor, the whiplash is too big. For your first fishing rod, you should not buy it. It is more convenient to learn how to handle tackle with an elastic fast action rod.
3. Pay attention to the place where the rod bends, the point where it bends the most. If only the tip of the rod bends when swinging, it has a fast action. If the greatest bend is closer to the middle, then this is a rod of medium order. If the bend of the rod extends beyond the middle, towards the handle, then this is a slow action rod, whippy. Whip rods are used in tackle that requires long casting.
