Given the cycle created between numeric->decimal and decimal->numeric, I 
can pretty much guarantee they will. In any case, I don't think implicit 
casting from numeric->decimal is a good idea since it can overflow. I'm 
not sure that the other direction is safe either... I can't remember 
offhand if casting correctly obeys typmod or not.

BTW, have you talked to Pavel about making these changes to his code? 
Seems a shame to needlessly fork it. :/
