Thanks for the hint, Shoaib. My question - and I should have phrased this
more carefully - related to the security of the various backup tactics.
Is it more secure to have a "backup user" with read permissions on all
databases, or is it more secure to have a dedicated Unix backup user -
with the .pgpass file in the home directory and all. If someone can, by
way of cracking, get in to the account of the backup Unix user, then the
postgres user's database account is also surrendered. If I have a
Postgres backup user (with read only permissions on all DB's), then even
if someone got into the unix account of the backup user, all they could do
is read DB data (versus delete or write over stuff).
Essentially it's the diffrenece between being *really* secure and *really
