Hi, What happens if you drop other indices with a similar size before starting the copy? It might just be the additional io-load (causing more checkpoints, more random io, etc) is causing the problems.
Could you share your config and hw info? Greetings, Andres -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
