Yeah, that was exactly the case that was top-of-mind when I was
complaining about static return buffers upthread.
It's not hard to make the ugliness go away: just let it strdup its
return value. The problem is that in the vast majority of usages it
wouldn't be convenient to free the result, so we'd have a good deal
of memory leakage. What might be interesting is to instrument it to
see how much (adding a counter to the function ought to be easy enough)
and then find out whether it's an amount we still care about in 2013.
Frankly, pg_dump is a memory hog already - a few more identifier-sized
strings laying about might not matter anymore.
(Wanders away wondering how many relpathbackend callers bother to free
its result, and whether that matters either ...)
