  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-9.5.  contrib often serves as a testbed for
 features before they are adopted into PostgreSQL proper:
 .
  adminpack      - File and log manipulation routines, used by pgAdmin
  btree_gist     - B-Tree indexing using GiST (Generalised Search Tree)
  chkpass        - An auto-encrypted password datatype
  cube           - Multidimensional-cube datatype (GiST indexing example)
  dblink         - Functions to return results from a remote database
  earthdistance  - Operator for computing the distance (in miles) between
                   two points on the earth's surface
  fuzzystrmatch  - Levenshtein, metaphone, and soundex fuzzy string matching
  hstore         - Store (key, value) pairs
  intagg         - Integer aggregator/enumerator
  _int           - Index support for arrays of int4, using GiST (benchmark
                   needs the libdbd-pg-perl package)
  isn            - type extensions for ISBN, ISSN, ISMN, EAN13 product numbers
  lo             - Large Object maintenance
  ltree          - Tree-like data structures
  oid2name       - Maps OIDs to table names
  pageinspect    - Inspection of database pages
  passwordcheck  - Simple password strength checker
  pg_buffercache - Real time queries on the shared buffer cache
  pg_freespacemap- Displays the contents of the free space map (FSM)
  pg_trgm        - Determine the similarity of text based on trigram matching
  pg_standby     - Create a warm stand-by server
  pgbench        - TPC-B like benchmark
  pgcrypto       - Cryptographic functions
  pgrowlocks     - A function to return row locking information
  pgstattuple    - Returns the percentage of dead tuples in a table; this
                   indicates whether a vacuum is required.
  postgresql_fdw - foreign data wrapper for PostgreSQL
  seg            - Confidence-interval datatype (GiST indexing example)
  sepgsql        - mandatory access control (MAC) based on SELinux
  spi            - PostgreSQL Server Programming Interface; 4 examples of
                   its use:
                   autoinc    - A function for implementing AUTOINCREMENT/
                                IDENTITY
                   insert_username - function for inserting user names
                   moddatetime - Update modification timestamps
                   refint     - Functions for implementing referential
                                integrity (foreign keys).  Note that this is
                                now superseded by built-in referential
                                integrity.
                   timetravel - Re-implements in user code the time travel
                                feature that was removed in 6.3.
  tablefunc      - examples of functions returning tables
  uuid-ossp      - UUID generation functions
  vacuumlo       - Remove orphaned large objects
