Add support for postgreSQL10

Hi, The support is partial, don't forget to modify the functions as here :) :

https://github.com/rafaelma/pgbackman/blob/73085166d0b8b98b450ca0e5806104c5394ff621/pgbackman/database.py#L3379 https://github.com/rafaelma/pgbackman/blob/73085166d0b8b98b450ca0e5806104c5394ff621/pgbackman/database.py#L3336 https://github.com/rafaelma/pgbackman/blob/73085166d0b8b98b450ca0e5806104c5394ff621/pgbackman/database.py#L3362

One of the major changes in Postgresql 10 is the change of some functions (XLOG=>WAL), It would therefore be necessary to make a routine that detects the server version to modify these SQL requests. Yours sincerely,

Thanks for the feedback.

You are right, good catch. Will do.
