Restore command

[Krysztophe]

pg_back is nice, but a newbie may not know in which order restore the dumps, which commands to use, especially in panic mode. Or ignore which base to restore. Or what to do with the different createdb.sql. Or what to do with the settings file.

Most people will ignore that the ALTER ROLE ... IN DATABASE ... must be searched and replayed.

A simple script, or even a basic README, should be generated to indicate which files are to be used and in which order.
