As an addition to my mail from January 2016 concerning graphics (https://www.postgresql.org/message-id/568A9148.30303%40purtz.de) I propose to use SVG (after switching to XML) - but not an SVG which is generated by Inkscape or similar tools. Those editors generate very ugly and chatty commands. This form is not easy to read or understand. Therefore we shall use nothing but a simple text editor and write every line by our self. The process is divided into two parts:
As a basis we shall develop an SVG library containing a bunch of "atomic" symbols of simple graphical elements (rectangle, arrow, ...) up to complex elements (magnetic disc, laptop, cloud, UML-elements, ...). The SVG routines creating those symbols shall accept parameters for position, size, rotation, colour, ... . This library shortens the individual SVG files, it ensures a consistent rendering of common graphical elements, it is diff-able, and it will reach a stable state - some day.
The real graphics shall use the elements of the library and add individual SVG elements. The rules for this part are the same as above: create SVG commands with vi (or similar), store it in git.
If such an approach works (we must distribute the docs across a wide range of different systems, a proof-of-system is necessary) and the community accepts my proposal, I would like to work on the library-part - starting after finishing my actual project in about 6 weeks from now. The attached file contains a very first draft as of Jan. 2016.
Kind regards
Jürgen Purtz

Hi %,
I am working with PostgreSQL documentation quite a few years now and I am almost happy. What I think is completely missing (especially if you compare to commercial product documentation) are pictures that illustrate a topic, e.g. the relation of instance->database->user/role->schema->objects.
Is there an agreement not to include that pictures for any reason? I can not promise that I find time for that in the near future but if that will be appreciated I am willing to spend time on that to make the documentation even better.
Regards
Daniel
