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,
