additional facilities for PostgreSQL
 The PostgreSQL contrib package provides several additional features
 for the PostgreSQL database. This version is built to work with the
 server package postgresql-8.1. contrib often serves as a testbed for
 features before they are adopted into PostgreSQL proper:
 .
  btree_gist - B-Tree indexing using GiST (Generalised Search Tree)
  chkpass - Password type for storing and comparing encrypted passwords
  cube - Type for n-dimensional "cubes"
  dbase - Inserts the contents of an xBase-style .dbf file into a
                   PostgreSQL table
  dblink - Functions to return results from a remote database
  dbmirror - Trigger-based databaase mirroring
  earthdistance - Operator for computing the distance (in miles) between
                   two points on the earth's surface
  fulltextindex - Full text indexing using triggers
  fuzzystrmatch - Functions for fuzzy string comparison (including Soundex)
  intagg - Integer aggregator/enumerator
  intarray - RD-tree data structure using GiST index
  isbn_issn - Type extensions for ISBN (books) and ISSN (serials)
  lo - Large Object maintenance
  ltree - data types, indexed access methods and queries for data
                   organized as a tree-like structures.

  pg_tgrm - Determine the similarity of text based on trigram matching
  pgbench - A simple program to run a benchmark test

                   moddatetime - Update modification timestamps
                   refint - Functions for implementing referential

                                integrity.
                   timetravel - Re-implements in user code the time travel
                                feature that was removed in 6.3.
  tablefunc - C functions which return setof scalar and setof composite
  tips - Micro HOWTOs
