    From the manual:

    PostGIS has begun a transition from the existing naming convention to
    an SQL-MM-centric convention. As a result, most of the functions that
    you know and love have been renamed using the standard spatial type
    (ST)     prefix. Previous functions are still available, though are not
    listed in this document where updated functions are equivalent. These
    will be deprecated in a future release.
