Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

* These routines are driven by the 'typbyval' and 'typlen' information,

|
* which must previously have been obtained by the caller for the datatype
|
|
* of the Datum. (We do it this way because in most situations the caller
|
