In PostgreSQL, do HASH operations provide inequality comparison?

Answer from AI
In PostgreSQL, HASH operations are used for fast equality comparisons, for example, in hash indexes. However, they do not support inequality comparisons (>, <, >=, <=).
Inequality comparison operations are implemented through other methods, such as B-tree indexes.
Therefore, HASH operations are suitable for equality checks but not for ordered comparisons.
