hello
the strange thing is -- what i've forgot to mention -- is that
PQerrorMessage returns an empty string, so from this i don't know the
source of the error.
how can I check if it is _really_ out of memory?
i have 1G RAM in the box, and shm values are set:
kernel.shmmax = 536870912
kernel.shmall = 536870912
Bye,

The point is, that geeks are not necessarily the outcasts
society often believes they are. The fact is that society
isn't cool enough to be included in our activities.
