On a related issue, so far I haven't considered about the way to output
the notice message at all :( In the current SR, it's always written to
stderr by the defaultNoticeProcessor by using fprintf, whether the
log_destination is specified or not. This is bizarre, and would need to
be fixed.
I'm going to set the new function calling ereport as the current notice
processor by using PQsetNoticeProcessor. But the problem is that only the
completed message like "NOTICE: xxx" is passed to such notice processor,
i.e., the error level itself is not passed.
So I wonder which error level should be used to output the notice message.
There are some approaches to address this;
1. Always use a specific level without regard to the actual one
2. Reverse-engineer the level from the complete message
3. Change some libpq functions so as to pass the error level to the notice processor
But nothing really stands out. Do you have another good idea?
