postgresql-16-periods

PERIODs and SYSTEM VERSIONING for PostgreSQL

This extension attempts to recreate the behavior defined in SQL:2016 (originally SQL:2011) around periods and tables with SYSTEM VERSIONING. The idea is to figure out all the rules that PostgreSQL would like to adopt (there are some details missing in the standard) and to allow earlier versions of PostgreSQL to simulate the behavior once the feature is finally integrated.

libmems1t64

library to support DNA string matching and comparative genomics

libMems is a freely available software development library to support DNA string matching and comparative genomics. Among other things, libMems implements an algorithm to perform approximate multi-MUM and multi-MEM identification. The algorithm uses spaced seed patterns in conjunction with a seed-and-extend style hashing method to identify matches. The method is efficient, requiring a maximum of only 16 bytes per base of the largest input sequence, and this data can be stored externally (i.e. on disk) to further reduce memory requirements.

postgresql-16-hll

HyperLogLog extension for PostgreSQL

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.
