Prior to PostgreSQL 7.3, every function that had the same name as a
data type, returned that data type, and took one argument of a
different type was automatically a cast function. This convention has
been abandoned in face of the introduction of schemas and to be
able to represent binary compatible casts in the catalogs. (The built-in
cast functions
still follow this naming scheme, but they have to be shown as
casts in <literal>pg_cast</> now.)
