Hello Gurus,
I would like to configure  our Pg db for OS  file system snapshot backup 
with Pg  WAL files, need to know if would be enough in pg db   to call :
|*SELECT* *pg_start_backup*('pitr_backup');
and next take the snapshot  and after
pg_stop the backup and close the WAL files . During this time  the full 
pg  db read/writes will continue.
Are any loss of data we should may be aware during this backup procedure?
env :RHES-64 bits with LVM directories, PG 9.0, the db size >150GB
Thank you
Isabella
