Package: postgresql-contrib-8.1 (8.1.13-0ubuntu0.6.06)

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"
 dbf2pg         - 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
 fti            - 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.
 oid2name       - Maps oids to table names
 ora2pg         - Conversion utility for Oracle database schemas
 pg_buffercache - Real time queries on the shared buffer cache
 pg_trgm        - Determine the similarity of text based on trigram matching
 pgbench        - A simple program to run a benchmark test
 pgcrypto       - Cryptographic functions
 pgstattuple    - Returns the percentage of dead tuples in a table; this
                  indicates whether a vacuum is required.
 seg            - Type representing laboratory measurements as floating-
                  point intervals
 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.
 tips           - Micro HOWTOs
 tsearch2       - Searchable text data type supporting indexed access
 user_locks     - User-level long-term locks
 vacuumlo       - Vacuum deleted large objects
 xml2           - Manipulate XML documents in the database
