Indeed, the code can crash on NULL values as the NULL checks
are missing or wrong in the functions.  Actually all the various
functions except newid() should be declared STRICT IMMUTABLE
thus immidiately avoiding problems with NULLs.

Could you reproduce the crash with this change?  I'll try
to play with this myself too.
