calendso=> UPDATE users SET email=LOWER(email);
ERROR: duplicate key value violates unique constraint "users.email_unique"
DETAIL: Key (email)=(free@example.com) already exists.
```
vs.
```
calendso=> CREATE UNIQUE INDEX "users.email_unique" ON "users" (email);
ERROR: could not create unique index "users.email_unique"
DETAIL: Key (email)=(Free@example.com) is duplicated.
```
I think it'll be easier to rectify for users if they try to run the migrations if the index stays in place.
