I have a column called "email" that users login with, thus I need to be able to lookup email very quickly. The problem is, emails are case-insensitive. I want foo@xxxxxxx to be able to login with FOO@xxxxxxx as well. There's two ways of doing this, that I can see: 1) Every time I lookup an email in the database, do a case-insensitive ilike, or cast both sides with LOWER(). I think both are slow, correct? 2) Every time the user updates or saves their email, store it in lowercase, and every time I lookup an email, pass in a lowercase email. This is somewhat of a bug farm because one might miss some little spot in a piece of code where an email is compared or updated. Is there any way to tell postgres to always store data in lowercase form, or just have a flat out case-insensitive column? Thanks!
