deferring/disabling unique index

Hi,

I need to know if there is a way to defer or disable a unique index on a
table during an update. One way would be to set indisunique to false,
perform update and then set to true. But, this seems to be an ugly
solution.

I've posted a similar message 6 months ago and at that time deferring
unique constraints was on a todo list. I wonder if this has been added
to 7.4.1 release. If not, what is the best way to disable an index on a
table?

Thanks.

Oleg
