Implement a new data type

От

Hello

I would like to implement a new data type next to char, number, varchar... for example a special "Money" type, but
I don't want to use extensions and the Create type command.  I want to implement it directly inside source code,
because I want to implement my new type at lower level, in order to perform some more sophisticated functions after.
Just as an example,  help the optimizer in its decisions.
How should I proceed ? Is it an easy task ?

Thanks
Mohand
