OK, that works for me.

One addition I'd like to include with the revised patch: a boolean
postgresql.conf option ('log_truncate_on_rotation', default false) to
truncate any existing log file by the same name. Default behavior here and
with Apache is to always append, but it's a useful feature for us because
it largely eliminates the issue of logs filling up the disk. You don't
want the log clobbered on restarts, so the idea is to only truncate during
time/size-based rotation, not on the initial open. Thoughts?
