right, currently it's very slow, working on improvements. The code is
in trunk, I will announce the native PostGIS support when it will be
ready for testing (roadmap is for July, unfortunately till June I need
to focus on other important task). In any case partial speed-up (for
random access and building areas for boundaries) should be committed
to trunk with few days.
