That difference in speed seems quite large. Too large. Are you batching your INSERTs into transactions (you should be in order to get good performance)? Do you have a ton of indexes on the table? Does it have triggers on it or some other thing (if so then COPY may well wind up doing the wrong thing since the triggers won't fire for the rows it inserts)? I don't know what kind of schema you're using, but it takes perhaps a couple of hours to insert 2.5 million rows on my system. But the rows in my schema may be much smaller than yours. -- Kevin Brown [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
