I'd do it this way. Plus either a CHECK condition on the table (email =
lowercase(email)) (this will reliably catch all cases, but you will
experience failures until you have found all cases)
Or a BEFORE trigger that converts email to lowercase. (This is mostly
transparent for storing, but I usually try to avoid triggers that modify
data like this. But that's probably just me.)
In either case, obviously you'll still need to change the code that is used
for retrieving and comparing email addresses.
