David Bear:
Yes. I agree with you.
\copy is really too brittle.
I wonder why \copy is not like oracle's sqlldr?
I think sqlldr is more powerful. When using sqlldr,we can specify the maximum error records we allow,and we can also specify the number we should commit in every transaction.
I think PostgreSQL should consider this.
Another aspect is also important. Oracle has better partition table facilities,it's especially suitable for large tables,as well as index partition concepts.But PostgreSQL has no such concepts.These are really important for large database.
I think if PostgreSQL can implement those above in the future.It will be more powerful and more suitable for large business application.
