Description: 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.
