cdist-type__postgres_extension - Manage PostgreSQL extensions

DESCRIPTION
|
||||
-----------
|
||||
This cdist type allows you to create or drop postgres extensions.
|
||||
This cdist type allows you to manage PostgreSQL extensions.
|
||||
|
||||
The object you need to pass to __postgres_extension consists of
|
||||
the database name and the extension name joined by a colon in the
|
||||
following form:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
dbname:extension
|
||||
|
||||
f.ex.
|
||||
The ``__object_id`` to pass to ``__postgres_extension`` is of the form
|
||||
``dbname:extension``, e.g.:
|
||||
|
||||
.. code-block:: sh
|
||||
|
||||
rails_test:unaccent
|
||||
|
||||
|
||||
**CAUTION!** Be careful when installing extensions from (untrusted) third-party
|
||||
sources:
|
||||
|
||||
| Installing an extension as superuser requires trusting that the extension's
|
||||
author wrote the extension installation script in a secure fashion. It is
|
||||
not terribly difficult for a malicious user to create trojan-horse objects
|
||||
that will compromise later execution of a carelessly-written extension
|
||||
script, allowing that user to acquire superuser privileges.
