An error context callback function might leak some memory into
ErrorContext, since those functions are run with ErrorContext as
current context. In the case where the elevel is ERROR, this is
no problem since the code level that catches the error should do
FlushErrorState to clean up, and that will reset ErrorContext.
However, if the elevel is less than ERROR then no such cleanup occurs.
In principle, repeated leaks while emitting log messages or client
notices could accumulate arbitrarily much leaked data, if no ERROR
occurs in the session.
To fix, let errfinish() perform an ErrorContext reset if it is
at the outermost error nesting level. (If it isn't, we'll delay
cleanup until the outermost nesting level is exited.)
The only actual leakage of this sort that I've been able to observe
within our regression tests was recently introduced by commit
