Hi all, this is the alpha version for the new email data type,
is not written as built in type but as plug in, Tome Lane and others
drove me in this direction.

The type is indexable and provide also conversion methods:

text <--> email
and the operator >>, is possible use it in select like:

select * from my_user where email >> 'hotmail.com';

this select will extract all records with an email inside
the domain 'hotmail.com'.

The validation routine is very simple, right now test only
the presence of character '@' (it's an alpha version), I'd like
to put it on pgfoundry but apparently my DNS are unable to resolve
www.pgfoundry.org. I'll put this version as soon the address become
available.

This is the first time that I wrote code for postgresql so please, if
you can, do a sort of code revision on it.

Comments are welcomed.

Regards
Gaetano Mendola.
