LLD is a new, high-performance linker. It is built as a set of reusable components which highly leverage existing libraries in the larger LLVM Project.

This module provides numeric data types for PostgreSQL that use numerals (words instead of digits) for input and output.

This PostgreSQL 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.
