Paketti: postgresql-hll (2.7-2.1)

HyperLogLog extension for PostgreSQL

This Postgres module introduces a new data type `hll` which is a HyperLogLog data structure. HyperLogLog is a **fixed-size**, set-like structure used for distinct value counting with tunable precision. For example, in 1280 bytes `hll` can estimate the count of tens of billions of distinct values with only a few percent error.

In addition to the algorithm proposed in the original paper, this implementation is augmented to improve its accuracy and memory use without sacrificing much speed.
