Strange.
I tried "strace -p17504", and this gave me just the following output:
sendto(7, "\7\0\0\0\003771\0\0\0\00224\0\0\0\017127.120.213.18"..., 968,

Looks like part of your query results being sent. Is it hung in that one
system-call?
Yes, I left it there for about ~1 hour, and that was all that ever came.
Does anyone have any further troubleshooting suggestions that I can do,
to figure out why this query have "crashed"?
Is the client locked/crashed too?
If it's connected over a network, is the connection still there?
We stopped the client application to see if that would make any
difference, but the connection and the query on the server side is still
there.
A strace of the client application before it was shut down simply showed:
strace -p6721
Process 6721 attached - interrupt to quit
accept(18, <unfinished ...>
so, not very helpfull.
The pg version is 8.2.9 on RHEL4
Fairly standard setup. I've seen various problems reported by selinux
oddities, but nothing quite like this.
We don't use selinux.
