In this paper, various tools for optimizing SQL queries were considered and the rationale for the need to apply optimization methods. As a result of studies of available optimization methods, their advantages and disadvantages are formulated. On the basis of studies of classical optimization methods, paired optimization methods were proposed. An analysis of their effectiveness was carried out in comparison with classical optimization methods using the example of a demo version of air transportation databases. Based on the results obtained, a technique was proposed for optimizing SQL queries in the PostgreSQL DBMS.
