I think the st_ prefix is now required,

This was previously an issue if you installed postgis into other than the public schema. The public schema reference was in a few locations, so you need to search it out in the function defs and remove it and recreate the function if you don't want to upgrade.

I have upgraded a number of databases to 1.5 from 1.4 and it seems to have fixed it... but I have also mucked it by not changing the search_path prior to running the upgrade, leaving me with multiple postgis function definitions!
