Hm, we may not want backtrace_on_internal_error to be on by default.
AFAICS, all ERRCODE_INTERNAL_ERROR are identifiable with the error
message, so it's sort of easy for one to track down the cause of it
without actually needing to log backtrace by default.

I see a merit in Peter's point. I like the idea of
backtrace_functions_min_level controlling backtrace_on_internal_error
too. Less GUCs for similar functionality is always a good idea IMHO.
Here's what I think:
1. Rename the new GUC backtrace_functions_min_level to backtrace_min_level.
2. Add 'internal' to backtrace_min_level_options enum
+static const struct config_enum_entry backtrace_functions_level_options[] = {
+ {"internal", INTERNAL, false},
+ {"debug5", DEBUG5, false},
+ {"debug4", DEBUG4, false},
3. Remove backtrace_on_internal_error GUC which is now effectively
covered by backtrace_min_level = 'internal';
Does anyone see a problem with it?
