Add sleep before/after retrieving timestamp in the user guide.
Add sleep before/after retrieving timestamp in the user guide.

Adding a sleep before was necessary since only adding a sleep after did not always work. This helps to ensure the backup stop time for the previous backup does not equal time-recovery-timestamp. The sleep after allows enough time between the time retrieval and dropping important_table so PostgreSQL can consistently recover to before the table drop.

Note that these issues were caused by picking a timestamp too close to the restore command or a database operation, not due to any problem in backup selection of the restore command.
