Well... in my mind I had also something more, Steven suggested. Mark a
query and execute it. The reason why I want such a support is, that I
don't want to copy queries e.g. to pgadmin

Well... also possible. Do you need some editor features on that buffer?

should be not too complicated for everyone in first step IMHO.

Well... This is something, I was thinking of not having -- at least on
versions. I just don't think it's needed to often by a developer. And
everyone else could use pgadmin/phpmyadmin/*

I second that there should be a blocking UI when running a query -- by
using the geany api it should be not often the issue anymore.
