I am currently using the pg_hotbackup Perl script to backup my production PostgreSQL database.  However, the next production database is going to be close to a terrabyte in size.  We feel that a tar cvzf command is not the correct OS backup solution to use.  Instead we would like to use lvmsnapshot.  Is anyone using the pg_hotbackup script but instead of the tar cvzf OS command are they using lvmsnapshot?

Or, is anyone using lvmsnapshot and doing point-in-time recoveries?
