pg_basebackup: Clean created directories on failure

Browse Source 
Like initdb, clean up created data and xlog directories, unless the new
-n/--noclean option is specified.

Tablespace directories are not cleaned up, but a message is written
about that.

By default, when <command>pg_basebackup</command> aborts with an
error, it removes any directories it might have created before
discovering that it cannot finish the job (for example, data directory
and transaction log directory). This option inhibits tidying-up and is
thus useful for debugging.

Note that tablespace directories are not cleaned up either way.
