Обсуждение: debug_print_plan

I cannot get debug_print_plan to print the query plan to the
log.  I have set it in the postgresql.conf file and bounced
the server.  The output is simply not there.  show shows
that the value is set, but no output.

If someone can respond Right Now I'd very much appreciate
it. I cannot get onto irc from this client site.

What's your log_min_messages setting?  According to the documentation,
debug_print_* needs DEBUG1 or lower.

    /*
     * Print plan if debugging.
     */
    if (Debug_print_plan)
        elog_node_display(DEBUG1, "plan", plan, Debug_pretty_print);

Looks like you also need to have server_min_messages <= DEBUG1.

Aha you are right. I tried this but set log min error statement
instead and so *that* didn't work.

Setting the right variable worked and I can now see the plan.

Thanks!!
