    In addition to procedures consisting of POSTQUEL statements, POSTGRES also supports procedures written in a conventtonal programming language as, for example LISP or C. Moreover, the concept of abstract data types is supported by POSTGRES, but only on a rather low level as far as the representation of an abstract data type is concerned. The representation is an unstructured storage area. Only the length of the area is given, i.e. there Is no strong typing as far as the representation of an abstract data type is concerned. This is also the method for passing parameters to functions written in LISP or C.
