I am 100% agree with you. What you are describing is a very good and useful technique for some maintenance operations.
My current goal is to increase performance in normal [almost ;)] OLTP mode of my application, so removing indexes for
sometime is not an option here.
And my question remains.
Is it Ok to use COPY BINARY FROM STDIN instead of multiple INSERTs?
