you need to strip the string apart using either regex which is
difficult to use or split_part()
http://www.postgresql.org/docs/8.3/interactive/functions-string.html
The update will look something like this...
Update customer set custfirstname = split_part(Name, ' ', 1) ,
custmiddlename = split_part(Name, ' ', 2) , custlastname =
split_part(Name, ' ', 3)
split_apart can give funky results if the data is not uniform.
