Its becoming a real Off topic so ill make it short :)

lets say one of the rows in the table is an unique index and it has the
following values ( each row ): 1, 2, 3, 4, 5

Deferable Update enable you to update the table like this: update table_name
set unique_row = unique_row + 1;

Currently postgres will abort when row 1 will get the forbidden value of 2
( 1 + 1 ) which is also the value of row 2.
