I am the only user of the system and at the moment I have only one
database user.

I only want the insdert/update triggers to be executed when I am
importing data. There might be situations where I need to intervene
"manually" and fix some data without the triggers being actioned.

How about creating a second user through whom the imports are done?

I could query current_user in the trigger and simply skip the trigger
actions for any other user. 

QUESTION: 
Or could I do something more sophisticated with privileges?
