Re: PostgreSQL XID exceeded crash.

Hi,

The platform as you have seen is Debian testing branch. I have activated 
log_statement but again nothing clear, the query that makes the system 
fail has nothing strange on it here is a dump.

I do not know how toget a stack trace and the "crash" does not provide a 
core dump :(. Could you explain how to obtain it?.

Thanks,

Maybe someone else has an idea?  The previous-to-last message below is
"server process exited with exit code 255".

That's very strange if the platform is Linux --- I was guessing it was
Windows.

Please try to get a core dump from the crash and provide a stack trace.

Another thing that would be useful is to turn on log_statement so we can
see the exact command causing the crash.
