What are the recommended ulimit settings. A single postgres connection that does an insert(with no other database activity) of say 6 million rows into a 15 column table (all integer columns) cannot complete due to an out of memory error This happens on a 4Gb Linux box with shmmax set to 1gb and about 50000 shared_buffers I would really appreciate any help ...
