I am developing a web system that uses postgres and postgis, my source
code is released under Apache2 licence (The customers has a copy of the
whole source reposotory). The server interacts using jdbc and a C
function for postgres. The client (java) interacts only with my server
application.

I think that this is safe, I'm doing wrong?
My software ​​has to use the GPL? if I can I'd like to use Apache2
licence for my source code.
