Table truncate question

От

I recently truncated a partitioned table.

When I look at the statistics for the table, it shows tuples inserted as zero (which I would expect), but it did not clear the value for tuples updated and tuples deleted.

Is this the expected behavior?  I would assume that the updated/deleted stats should also get cleared.

 

I am running PG 8.1.4 on Windows.

Stats get updated by the ANALYZE command.  Run it on the table and check
again.
