Firstly, I'm not sure what this message has to do with the thread
"Trigger Function and backup".

Secondly, please show your table definition.

And Finally, the round() mathematical function is ill-defined.  People
have been arguing over this for decades.  Choose either ceil() or
floor() to get a more precise result with appropriate addition or
subtraction of 0.5 to get the "rounding" effect you seem to desire.
