About PostgreSQL 7.2B
PostgreSQL 7.2 is currently in beta, and people might be tempted to try to use it with PostGIS 0.6.2. Unfortunately, due to a change in the API hooks for the GiST index, PostGIS 0.6.2 will not work with PostgreSQL 7.2. When PostgreSQL 7.2 is officially released, work on converting PostGIS to support the new indexes will begin. We might drop support for the 7.1 series at that time.
