Thread: pgsql: Fix documentation of pg_start_backup and pg_stop_backupfunction

Fix documentation of pg_start_backup and pg_stop_backup functions.

This commit adds the description that "non-exclusive" pg_start_backup
and pg_stop_backup can be executed even during recovery. Previously
it was wrongly documented that those functions are not allowed to be
executed during recovery.

Back-patch to 9.6 where non-exclusive backup API was added.
