When I called pg_log_current_query_plan() to send the signal to
the backend executing the above query, I got the following log message.
I think that this is not expected message. I guess this issue happened
because the information about query text and plan is retrieved
from ActivePortal. If this understanding is right, ISTM that we should
implement new mechanism so that we can retrieve those information
even while nested query is being executed.
I'm now working on this comment.
One idea is to define new global pointer, e.g., "QueryDesc *ActiveQueryDesc;".
This global pointer is set to queryDesc in ExecutorRun()
(also maybe ExecutorStart()). And this is reset to NULL in ExecutorEnd() and
when an error is thrown. Then ProcessLogCurrentPlanInterrupt() can
get the plan of the currently running query from that global pointer
instead of ActivePortal, and log it. Thought?
