[PATCH] Store Extension Options

Hi all,

The main goal of this patch is enable to an user the capability to store
options
(relations and attributes) related to extensions by using a fixed prefix
called 'ext' in
the defined name. It's cant be useful for replication solutions.

So, with this patch we can do that:

ALTER TABLE foo
SET (ext.somext.do_replicate=true);

When 'ext' is the fixed prefix, 'somext' is the extension name,
'do_replicate' is the
extension option and 'true' is the value.

Also we can use this form to define storage options to indexes and
per-attribute
options.

Regards,
