it all depends on the number of drives, the type of drives
and if raid is being done in hardware or software.
A three drive raid 5 array in software with older drives
is probably going to be slower than a single 7200rpm ata100 drive.
Not that this is what you have, just pointing out that it's po

Not exactly sure about postgres but in general LIKE can
only use an index in the case of LIKE "Something%"
LIKE "%Something" or LIKE "%Something%"
won't use an index since it would have to scan the entire
index to find all matches.

Have you done any benchmarks with a prototype of your application.
Based off of some of the numbers I've been seeing with my testing,
I would not be surprised if a single pIII 1ghz box with a decent disk

cheaper than some big smp
I think there's an option to log the pid in postgresql.conf in 7.1

As of version 7.1 postgres uses write ahead logging which is what
you are looking for.
As for backups, currently your only option is full dumps of the entire
db or full dumps of individual tables.
Some folks are working around this by using replication to
a secondary server with rserv (in contr
Hi, I'm trying to figure out what some reasonable settings would
be for kernel parameters like shared memory and max open files.
I've read the section of the manual but it doesn't seem to give
any rule of thumb based on number of users or frequency of queries.
With my load testing I definitely bu

I personally would like to see 8byte OIDs or at least int8 sequences, I'm
a little worried about the pain of managing a potential rollover when I'm
using sequences as a replication key between servers.

I agree that they are very handy. They become a major pain in
the butt when you start doing replication between servers.
For instance if you fail over to a standby server and you
forget to update it's sequence first, merging data later
becomes a nightmare. I'd like to have int8 sequences and

If there's no simple way to do this, I think I found an example of what I

I've noticed that select max(the_primary_key) from some_table
does a table scan. Is there any plan to implement max/min calculations
using index lookups if the appropriate index exists?
Thanks,
Alex.
I'm willing to do some writing if someone will explain things to me.
I've pretty much disected all the sql used by Rserv.pm to see what it
does so I've got a decent head start.
The two questions that are holding me up at this point are:
1. which column do you specify for setting up the replicatio
I've heard of other people running databases on a Netapp Filer
I think this is generally ok because the netapp has a special
write cache in NVram and that's what makes it so fast.

Is there any way to have up to the minute recovery from a disk
failure in postgres?
Is there a timeframe for the recover from WAL feature?
Thanks,

Sounds like you need to use a trigger set to
fire after the insert on table A
