MariaDB is a database server that offers drop-in replacement functionality
for MySQL. MariaDB is built by some of the original authors of MySQL, with
assistance from the broader community of Free and open source software
developers. In addition to the core functionality of MySQL, MariaDB offers
a rich set of feature enhancements including alternate storage engines,
server optimizations, and patches.
MariaDB is primarily driven by developers at Monty Program, a company
founded by Michael "Monty" Widenius, the original author of MySQL, but
this is not the whole story about MariaDB. On the "About MariaDB" page you
will find more information about all participants in the MariaDB community,
including storage engines XtraDB and PBXT.
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.
