Hi,
One simple question. For 125 or more checkpoint segments (checkpoint_timeout
is 600 seconds, shared_buffers are at 21760 or 170MB) on a very busy database,
what is more suitable, a separate 6 disk RAID5 volume, or a RAID10 volume?
Databases will be on separate spindles. Disks are 36
7.4 is the pg version BTWgoing to switch to 8 if it's worth it.

of indigestion.

Interesting; do they use an overwriting storage manager like Oracle, or
a non-overwriting one like Postgres?

Alvaro's "a". This is further suppor
