I would like to get someone's recommendations on the best initial settings for a dedicated PostgreSQL server. I do realize that there are a lot of factors that influence how one should configure a database. I am just looking for a good starting point. Ideally I would like the database to reside as much as possible in memory with no disk access. The current database size of my 7.x version of PostgreSQL generates a 6 Gig file when doing a database dump.
Dedicated PostgreSQL 8.2 Server Redhat Linux 4.x AS 64 bit version (EM64T) 4 Intel Xeon Processors 20 Gig Memory Current PostgreSQL database is 6 Gig file when doing a database dump /etc/sysctl.conf file settings: # 11 Gig kernel.shmmax = 11811160064 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default = 262144 net.core.rmem_max = 262144 net.core.wmem_default = 262144 net.core.wmem_max = 262144 postgresql.conf file settings (if not listed then I used the defaults): max_connections = 300 shared_buffers = 10240MB work_mem = 10MB effective_cache_size = 512MB maintenance_work_mem = 100MB Any suggestions would be appreciated!
