Hi,

The other RDBMS pundits say that any unlogged operation like truncate table will make the backup completely useless and no recovery will be possible after the point unlogged operation was performed, for any DB objects.

I do not agree to this. I feel only the object on which unlogged operation was performed, will be useless ( corrupt).

Right? Please send your operation before I try it on my production system.
