The contrib utilities from the PostgreSQL distribution
This is the port for all stuff that comes in the contrib subtree of the postgresql distribution. This subtree contains porting tools, analysis utilities, and plug-in features that are not part of the core PostgreSQL system, mainly because they address a limited audience or are too experimental to be part of the main source tree. This does not preclude their usefulness.
Each subdirectory contains a README file with information about the module. Some directories supply new user-defined functions, operators, or types. After you have installed the files you need to register the new entities in the database system by running the commands in the supplied .sql file. For example,
$ psql -d dbname -f module.sql
The .sql files are installed into /usr/local/share/postgresql/contrib
For more information, please see /usr/local/share/doc/postgresql/contrib/README*
This software is part of the standard PostgreSQL distribution.
