Hi pgsql-list-members,
I currently write a small script that deletes outdated xlog-files from
my backup-location.
Because I do not want to rely on creation-date, I found it usable to use
the result of
ln | sort -g -r
Thus the newest WAL xlog-file is on top and I can delete all not needed
files at the bottom of the list.
Warning, this is NOT SAFE to do. You should NEVER delete "outdated"
xlog files, unless you appreciate RANDOM CORRUPTION of your data.
I think he's talking about deleting pg_xlog files that are being used
for PITR from the backup machine after they've been applied.
But I'm not sure that's really what he meant or not.
