Hi, on a server running 8.4 I observe that, since a while, the pg_attribute table is growing enormously. Soon after reloading I have one file ls -s 1249 1048580 1249 a day later this is 1048580 1249 1048580 1249.1 1048580 1249.10 1048580 1249.11 1048580 1249.12 1048580 1249.13 1048580 1249.14 1048580 1249.15 682212 1249.16 1048580 1249.2 1048580 1249.3 1048580 1249.4 1048580 1249.5 1048580 1249.6 1048580 1249.7 1048580 1249.8 1048580 1249.9 4316 1249_fsm 24 1249_vm and 5 days later the system had arrived at 102 files The server is running since quite some time, without any major change. The workload is mostly reading, a little text updates and a little more binary updates. Every two weeks or so the database is recreated and reloaded The total size of data is growing slowly (say a rate of 10% per year) Regards Wolfgang Hamann
