I think one use-case that I'd personally at least would like to see
covered is being able to get backtraces on all warnings. How would
that be done with this setting?

backtrace_on_error = all
backtrace_min_level = warning

In that case backtrace_on_error seems like a weird name, since it can
include backtraces for warnings if you change backtrace_min_level. How
about the following aproach. It still uses 3 GUCs, but they now all
work together. There's one entry point and two additional filters
(level and function name)

# Says what log entries to log backtraces for
log_backtrace = {all|internal|none} (default: internal)

# Excludes log entries from log_include_backtrace by level
backtrace_min_level = {debug4|...|fatal} (default: error)

# Excludes log entries from log_include_backtrace if function name
# does not match list, but empty string disables this filter (thus
# logging for all functions)
backtrace_functions = {...} (default: '')


PS. Other naming option for log_backtrace could be log_include_backtrace
