Indeed.  Any code path of pg_dump calling buildACLQueries() clears up
things, and I think that it is a better practice to clean up properly
PQExpBuffer stuff even if there is always the argument that pg_dump
is a tool running in a "short"-term context.  So I will backpatch that
unless there are any objections from others.

The part I am actually rather amazed of here is that I don't recall
seeing Coverity complaining about leaks after this commit.  Perhaps it
just got lost.
