Openlayers (.org) has some nice editing tools and you can use google
layer as background for going after it. Then you'll need some javascript
to communicate to a backend for saving what you draw. I'd look at tinyows
if I were you. It saves directly in postgis.

Doesn't have to do with luck.
Can't figure things out using proprietary software.
Do yourself a favor and use software you can look into.

Topology was available since PostGIS 1.1.0.
But what you get in binary packages isn't necessarely what was available
at the source level. You should be able to install your own version
of PostGIS and PostgreSQL if you can't convince the university to install
it themself.
