-  These are user-defined functions that can be bound to a Postgres backend
-  and called by Postgres to execute SQL functions of the same name.
-
-  The calling format for these functions is defined by the CREATE FUNCTION
-  SQL statement that binds them to the backend.
-
-  NOTE: this file shows examples of "new style" function call conventions.
-  See funcs.c for examples of "old style".
