Hi, I have a Linux Server (Debian) with Postgres 8.3 and I have problems with a massive update, about 400000 updates/inserts. If I execute about 100000 it seems all ok, but when I execute 400000, I have the same problem with or without a transaction (I need to do with a transaction) increase memory usage and disk usage. With a execution of 400.000 inserts/update server begin woring well, but after 100 seconds of executions increase usage of RAM, and then Swap and finally all RAM and swap are used and execution can't finish. I have made some tuning in server, I have modified: -shared_buffers 1024 Mb -work_mem 512 Mb -effective_cache_size 2048Mb -random_page_cost 2.0 -checkpoint_segments 64 -wal_buffers 8Mb -max_prepared_transaction 100 -synchronous_commit off
what is wrong in this configuration to executes this inserts/update? Server has: 4Gb RAM, 3GB Swap and SATA Disk with RAID5 Thanks
