Hallo Birgit The max distance function was actually not implemented until
version 1.5There were some ideas about the function earlier that by some reason
made the sql-part of the function exist.But now it is there, so the
recomendation is, upgrade to PostGIS 1.5.1. The function has also changed name
so now it is
calledST_Maxdistancehttp://postgis.org/documentation/manual-1.5/ST_MaxDistance.html
Hope that helpsNicklas
