How to handle PhD student who expects help with technical problems? I am a postdoc supervising a PhD student in Computer Science. 

Unfortunately, I have a lot on my plate and I cannot help him with the solution of the technical problems (they require a lot of time to solve them). The PhD student often gives me some tasks and I execute them to help him go forward with his research. 

What are the suggestions you have? Should I talk about it with my Professor and maybe find a more suitable advisor for him?
Honestly, in my experience, I did not meet many PhD students who receive technical help from a Postdoc, but I could be wrong of course. 

I would just like to do the best for him and for me. 

Thanks for your ideas.
Strategically, it might be a good idea to prioritize helping the PhD student. You might gain some second authorships on papers, credit for PhD student supervision (which you will need for your next career step), and make a potential collaborator for life. It's a win-win situation.

It's a sign of a well-managed group if PhD students have access to experienced people who can give them technical guidance. In a small group, that person can be the PI. In a big group, PIs often hire post-docs to do that job for them.
