In this case, correction is to remove now unused fields from struct.
Since these were unused and full of garbage anyway, no version change.

so that we won't try to attach any context printouts to messages that get
emitted while exiting.  Per report from Dennis Koegel, the context functions
won't necessarily work after we've started shutting down the backend, and it
seems possible that debug_query_string could be pointing at freed storage
as well.  The context information doesn't seem particularly relevant to
such messages anyway, so there's little lost by suppressing it.

Back-patch to all supported branches.  I can only demonstrate a crash with
log_disconnections messages back to 8.1, but the risk seems real in 8.0 and
before anyway.

catalog entries via SearchSysCache and related operations.  Although, at the
time that these callbacks are called by elog.c, we have not officially aborted
the current transaction, it still seems rather risky to initiate any new
catalog fetches.  In all these cases the needed information is readily
available in the caller and so it's just a matter of a bit of extra notation
to pass it to the callback.

Per crash report from Dennis Koegel.  I've concluded that the real fix for
his problem is to clear the error context stack at entry to proc_exit, but
it still seems like a good idea to make the callbacks a bit less fragile
for other cases.

Backpatch to 8.4.  We could go further back, but the patch doesn't apply
cleanly.  In the absence of proof that this fixes something and isn't just
paranoia, I'm not going to expend the effort.
