Update:
< * Allow DEFERRABLE UNIQUE constraints?
> * Allow DEFERRABLE and end-of-statement UNIQUE constraints?
>
> This would allow UPDATE tab SET col = col + 1 to work if col has
> a unique index. Currently, uniqueness checks are done while the
> command is being executed, rather than at the end of the statement
> or transaction.
