OK, is that what everyone wants? I think that is what the patch already
does.
I think having multiple queryids used in a single cluster is much too
confusing to support. You would have to label and control which queryid
is displayed by pg_stat_activity and log_line_prefix, and that seems too
confusing and not useful.
