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 Note that this is now superseded by built-in referential integrity.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 . PostgreSQL is an object-relational SQL database management system.
