postgresql-contrib-9.5

additional facilities for PostgreSQL

Description

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                               now superseded by built-in referential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.
