postgresql-contrib-8.4 8.4.2-1~hardy1 (ia64 binary) in ubuntu hardy

 The PostgreSQL contrib package provides several additional features
 for the PostgreSQL database. This version is built to work with the
 server package postgresql-8.4. 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
  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.
  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                                now superseded by built-in referential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.
  tablefunc - examples of functions returning tables
  uuid-ossp - UUID generation functions
  vacuumlo - Remove orphaned large objects
 .
