Package: postgresql-contrib-8.2 (8.2.7-1) [universe]

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-8.2. 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
 intagg         - Integer aggregator/enumerator
 intarray       - Index support for arrays of int4, using GiST
 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
 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
 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.
 seg            - Confidence-interval datatype (GiST indexing example)
 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                               now superseded by built-in referential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.
 tsearch2       - Full-text-index support using GiST
 vacuumlo       - Remove orphaned large objects
 xml2           - Manipulate XML documents in the database

PostgreSQL is an object-relational SQL database management system.
