Code pointers for replace HSQLDB for Firebird

Hi guys!

As suggested by Cecric and Muthu, I'm here to ask some code pointers to
work in the HSQLDB replacement for Firebird.

I'm reading https://bugs.freedesktop.org/show_bug.cgi?id=51781 from Lionel,
and trying to understand what needs to be done to achieve this, but some
code pointers are better!

I know that this task is not easy, but, if someone could help me, I believe
we can remove some Java code from base :)

Thanks since now guys!
