PostGIS Function Support Matrix
Regina crafted matrix of functions available in upcoming PostGIS 1.5. Currently, PostGIS 1.5 is available from trunk in the Subversion repository.
The PostGIS 1.5 documentation is available under the manual-svn node and here is the PostGIS Function Support Matrix.
Regina, great job!
