The PostgreSQL contrib tree

---------------------------

This subtree contains tools, modules, and examples that are not

maintained as part of the core PostgreSQL system, mainly because

they only address a limited audience or are too inelegant to be

sold as an official feature. That, however, does not preclude

their usefulness.

This subtree contains utilities, conversion tools, and 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. Most items can be built with `gmake all' and installed

with `gmake install' in the usual fashion, after you have run the

`configure' script in the top-level directory. 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,

* Allow ability to easily build only certain interfaces (Marc)

* Remove or relicense modules that are not under the BSD license, if possible
