Log Message:
-----------
Move to referential integrity section:

o 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.
