Before thinking of a solution for this in PG, I dont
see why you need this requirement in the first place:
whay should the very same e-mail be both verified and
unveryfied? And even more - why should be more then one
row telling you this very same e-mail is unverified?
Is this only an example which does not serve very well
or is there a bigger picture?
