Re: First SVG graphic

The graphic for dump/restore is transferred from 'pg_dump utility' 
chapter to the 'backup and restore' chapter in sgml/backup.sgml. In this 
chapter I made a lot of textual changes to explain the relation between 
pg_dump, pg_restore and psql in more detail. Especially I tried to 
introduce a more stringent use of terms, eg: avoiding 'archive' because 
this term is used with a different meaning in the PITR chapter. (It 
would be a good idea to do the same for the description of the pg_dump 
utility.) Because I'm not a native English speaker, feel free to correct 
my wording.

The list of figures as well as lists of other prominent elements are 
removed. 'lists in TOC' seems to be a topic of its own and will be 
resumed later.

Kind regards, Jürgen
