I seem to recollect reading here that I can't have concurrent COPY on the same table because of the lock. To give an example: If I have a large file with say 400 million rows, can I first split it into 10 files of 40 million rows each and then fire up 10 different COPY sessions , each reading from a split file, but copying into the same table. I thought not. It will be great if we can do this.
