Re: Does error within transaction imply restarting it?

If you're really brave you can try this change in
backend/tcop/postgres.c:

        if (sigsetjmp(Warn_restart, 1) != 0)
        {
                time(&tim);

                if (Verbose)
                        TPRINTF(TRACE_VERBOSE, "AbortCurrentTransaction");

-               AbortCurrentTransaction();
                InError = false;
                if (ExitAfterAbort)
                {
                        ProcReleaseLocks(); /* Just to be sure... */
                        proc_exit(0);
                }
        }

Absolutely no guarantee, there's probably more to it. Hmm, I wonder, maybe
not.

Becoming one yourself or throwing large amounts of cash at the existing
ones. :) Trying the above and tracing down any arising problems might be a
start though.
