    Update EmailAddress index to case insensitive for Pg
    
    EmailAddress is case insensitive in RT(technically, name part could be
    sensitive according to RFC, but it's confusing and rarely used in real
    world). When we call RT::User::LoadByEmail, the WHERE part of generated
    SQL in Pg is actually like:
    
        LOWER(EmailAddress) = LOWER(?)
    
    Thus we need to adjust index accordingly, which is also consistent with
    the one in Oracle.
