Re: Strange error (Socket command option unknown)

Oops!  That was pretty irresponsible from me, not providing
that information!  :-(

Anyway, it's postgres 7.2.3 running on a RedHat 7.3 Linux
system, on a dual Athlon CPU (presumably installed
properly -- i.e., with the SMP kernel), with 1GB of
memory.

I installed postgres from the source, and changed the
parameters related to the shared buffers; I put something
around 250MB dedicated to shared buffers.

At peak times, we estimate that the system may do
something around 10 to 20 SQL statements per second;
maybe 70% to 80% of those are insert statements.  The
largest table has around a million records (we clean it
up weekly, since it would otherwise keep growing to
infinity).

Sorry for the lack of information in my initial post!  I
hope this will increase the chances that someone will
be familiar with the problem and can guide me to find
a solution!

Thanks,

Carlos
