Attached is my (admittedly horrible) attempt to add some comments to
elog.c regarding this issue. Reviewing this, I'm not sure the
performance concern is really an issue (given that the user could choose
to enable it or not), but clearly the other issue is a concern.

Improve comments at the top of elog.c
Add in some comments about how certain usually available backend
systems may be unavailable or which won't function properly in
elog.c due to the current transaction being in a failed state.
