Added a note to the docs that pg_start_backup can take a long time to 
finish now that we spread out checkpoints:

*** doc/src/sgml/backup.sgml    1 Feb 2007 00:28:16 -0000       2.97

        It does not matter which database within the cluster you connect 
to to
        issue this command.  You can ignore the result returned by the 
function;
!      but if it reports an error, deal with that before proceeding.

Note that

checkpoint,
!      and if one is already running it has to wait for it to finish 
first. You
!      can adjust <varname>checkpoint_completion_target</varname> to 
perform the
!      checkpoints more aggressively.
