I have one process which writes a single float into 300 columns once per
second. I then run 4 process, from remote computers, to query a small
subset of the latest row.
I have even commented out everything in the query programs, all they do
is sleep, and the associated postmaster still sucks up 15% - 20% CPU.
Computer is a P4 /w 1Gig memory, all disk access is local. RH9 /w stock
postgresql-7.3 installed.

Could anyone explain about the max_connections in postgres?
We ran into the connection limit on one of our production servers. One reason
is that we have more apps that use postgres running on it (RT3 and Webcollab
were added not long ago). Webcollab, for instance, seems to keep 7 postmaster
processes all to itself. Is this normal? Does postgres work similarly to
how apache handles spawning spare...

Hi all!
I have a big problem installing postmaster as a service under Windows XP
with cygwin. I already installed postgresql on 2 machines without
problems but this machine really seem to don't like postgresql ;) I do
exactly the procedure indicated in the README file but I always got the
same problem with this machine. When I try to start postmaster
who was previously installed as a service with
the command , I always got the same...

Hi,
I recently upgraded to postgresql 7.4 and I am having a problem with
postmaster using lots of memory for a query (keeps growing even up to
400MB+ till I stop postgresql ). I don't recall this ever happening with
7.3 with the exact same query but on different data (just as much data tho,
or even more). Happened on 7.4 so I upgraded to 7.4.1. Is HashAggregate
something new in 7.4? If I have time and disk space I'll downgrade to 7.3.3...

I'm writing a small test harness. I have two threads. One that starts
the postmaster and another that does all the testing and finally stops
the postmaster with a pg_ctl stop. At present, the second thread starts
with a sleep sufficient to ensure that the postmaster is running. Is
there a proper way to test when the postmaster is ready to receive commands?
Kind regards,
Thomas Hallgren

Dear peoples,
We had an oddness today with one of of postgres servers (Dell 2 CPU box running linux) and postgres 7.4. The server was under heavy load (50+ for a 1 minutes spike; about 20 for the 15 minute average) with about 250 connections (we still don't understand the heavy load itself).
Looking in the logs I see:
2004-11-13 13:30:28 LOG: unexpected EOF on client connection

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
