This module is a set of shared libraries which implement an API for debugging pl/pgsql functions on PostgreSQL 8.4 and above. The pgAdmin project (http://www.pgadmin.org/) provides a client user interface as part of pgAdmin III v1.10.0 and above, and pgAdmin 4.

This package contains the OpenCV (Open Computer Vision) shape descriptors and matchers runtime libraries.

Debian version numbers, used to version Debian binary and source packages, have a defined format, including specifications for how versions should be compared in order to sort them. This package implements a "debversion" type to represent Debian version numbers within the PostgreSQL database. This also includes operators for version comparison and index operator classes for creating indexes on the debversion type.

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.

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

postgresql-mysql-fdw is a PostgreSQL extension implementing a Foreign Data Wrapper (FDW) to access MySQL data from PostgreSQL.
