Research direction

The issue names KLL float and double sketches and classic quantile sketches, but no files, tests, or entry points. Start by locating the existing quantile-sketch functions and their tests in the PostgreSQL extension, then determine how statistical tests are exposed. Done means the Kolmogorov-Smirnov test is available for each listed sketch variant with corresponding test coverage.
