I would like to have dynamically loaded drivers in
HSQL but I don't like to use something like
hs-plugins. The problem with it is that you have to
load at runtime a copy of all packages which are
required from the dynamically loaded objects. In our
case this is the base package. We already have one
copy of base package which is already linked with the
program and you have to load a second copy just in
order to link the drivers. This has a significant
drawbacks to me. First of all this is a waste of space
and the second is that it might not work properly with
the static variables in base. I am sure that soon or
later we will have proper support for .dll under
Windows as well as we already have .dynlib under
MacOS. It will improve the things and then I will add
dynamic drivers.

Cheers,
