[postgis-users] PostGIS license

[Paul Ramsey]

If you are redistributing a modified version of PostGIS, then you have 
to redistribute the source code to that modified version. There are no 
GPL issues between your client software and PostGIS, your client is a 
separate application, communicating with the PostGIS/PostgreSQL 
application via a standard database interface.
