Can we add extra line on top of the result buffer?

It's a tiny detail, but would make pretty tables work better :D

Cell font-locking is taken from https://github.com/Fuco1/sql-workbench if you are interested, I can make a patch to put it in this package also.

Sure, go ahead. As a side note, I think that I saw another SQL emacs package doing a very nice representation of the result and I was planning to incorporate it but I switched jobs and I stopped using the package in my real-life job. I will look for that package.
